0:00:00 > 0:00:05Now on BBC News, it's time for Click.
0:00:05 > 0:00:09This week: 3-D printed legs.
0:00:09 > 0:00:11Careless cash machines.
0:00:11 > 0:00:13And aliens.
0:00:13 > 0:00:18Lots and lots of aliens.
0:00:40 > 0:00:42I've always wanted to go into space.
0:00:42 > 0:00:45Hey, I'm a future boy, always have been.
0:00:45 > 0:00:49And I'm lucky to be living in a time when the beauty of the universe
0:00:49 > 0:00:51is being brought to life.
0:00:51 > 0:00:55From earth you can now photograph amazing skies, if you know
0:00:55 > 0:00:58what you are doing.
0:00:58 > 0:01:00Which the entrants for this years Insight Astronomy Photographer
0:01:00 > 0:01:07of the Year Awards clearly do.
0:01:07 > 0:01:15Actually going into space though is still a pipe dream for me.
0:01:15 > 0:01:19Unless you count shoddy TV effects like this.
0:01:19 > 0:01:22Oh, and videogames of course.
0:01:22 > 0:01:25If you count video games I have already been across the galaxy.
0:01:25 > 0:01:28There are a number of games around now you see which let you go
0:01:28 > 0:01:31absolutely anywhere.
0:01:31 > 0:01:33The question is, would you want to?
0:01:33 > 0:01:37Marc Cieslak has been to meet the makers of what is quite possibly
0:01:37 > 0:01:42the most universal game yet.
0:01:46 > 0:01:49I grew up reading sci-fi books, looking at the covers,
0:01:49 > 0:01:52when I close my eyes and think of science-fiction I think of that.
0:01:52 > 0:01:56I think of a lone astronaut stood on a desolate planet with a couple
0:01:56 > 0:01:59of other huge planets hanging in the horizon and these kind
0:01:59 > 0:02:06of wild and crazy worlds.
0:02:07 > 0:02:12No Man's Sky is a space exploration game.
0:02:12 > 0:02:17It encourages the player to discover strange new worlds and lifeforms.
0:02:17 > 0:02:19There is trading and commerce.
0:02:19 > 0:02:24As well as allowing people to blow stuff up.
0:02:24 > 0:02:28All in a playable universe which is so big the games
0:02:28 > 0:02:35own designers predict most players won't even experience one percent
0:02:35 > 0:02:40of the worlds the game has to offer.
0:02:40 > 0:02:44It might be a game with a gigantic exotic alien universe to explore
0:02:44 > 0:02:48but it has been created in these tiny offices beneath a taxi
0:02:48 > 0:02:52company in Guildford.
0:02:54 > 0:02:59Indie games company Hello Games consists of just 11 people.
0:02:59 > 0:03:07The team's previous credits include fun stunt riding game Joe Danger.
0:03:07 > 0:03:13No Man's Sky is the brainchild of Sean Murray, who,
0:03:13 > 0:03:17along with this tiny team, has found a clever way to fashion
0:03:17 > 0:03:21this gigantic game and it's all thanks to maths.
0:03:21 > 0:03:25We are trying to build an entire universe and we can't build that
0:03:25 > 0:03:29by hand, normally when you make a game it's a series of levels
0:03:29 > 0:03:36and some artist or designer has built every one of those
0:03:36 > 0:03:43levels piece by piece, arranged all the furniture
0:03:43 > 0:03:45and everything like that.
0:03:45 > 0:03:48But we want to build something of a huge, huge scale.
0:03:48 > 0:03:51We just can't do that on our own, we're this tiny indie team,
0:03:51 > 0:03:54so what we do is we use the computer to build it.
0:03:54 > 0:03:58We create a bunch of rules, a set of maths and the computer runs that,
0:03:58 > 0:04:01we effectively teach the computer the rules that we think we need
0:04:01 > 0:04:02to build a universe.
0:04:02 > 0:04:05The computer goes off and generates it, builds it for you.
0:04:05 > 0:04:08This process is called procedural generation and it is how everything
0:04:08 > 0:04:09in the game is made.
0:04:09 > 0:04:12From the planets to the aliens to the ships to the smallest
0:04:12 > 0:04:14blade of grass.
0:04:14 > 0:04:17It's not random, those rules are there for a reason.
0:04:17 > 0:04:21What we are trying to do is create a set of rules and formula
0:04:21 > 0:04:25that we feel creates a nice looking universe.
0:04:25 > 0:04:31The size of the universe is incredibly big.
0:04:31 > 0:04:35There are a lot of planets, if you were to visit them
0:04:35 > 0:04:39all there would be 18 Quintilian which is this huge number,
0:04:39 > 0:04:44it's like 2 to the power of 64.
0:04:44 > 0:04:48It's a hard number to comprehend.
0:04:48 > 0:04:51The way I normally say it is like if you were to discover
0:04:51 > 0:04:55a planet or a planet was to be discovered in No Man's Sky every
0:04:55 > 0:04:58second it would take about 500 billion years for them
0:04:58 > 0:05:02all to be discovered.
0:05:02 > 0:05:05With its first reveal back at E3 in 2014 this game generated
0:05:05 > 0:05:07a considerable amount of anticipation as well as
0:05:07 > 0:05:10hype amongst gamers.
0:05:10 > 0:05:13I'm feeling a lot of emotions right now.
0:05:13 > 0:05:17However some of this attention hasn't all been positive.
0:05:17 > 0:05:20One gamer claims to have purchased a copy of the game ahead
0:05:20 > 0:05:25of release for ?1200 via eBay.
0:05:25 > 0:05:27After posting clips online he claimed it's possible to reach
0:05:27 > 0:05:30the centre of the game's universe in just 30 hours.
0:05:30 > 0:05:32This is a task developers have suggested would actually take
0:05:32 > 0:05:37about 100 hours of playtime.
0:05:37 > 0:05:44Sean Murray has implored fans to avoid these online spoilers.
0:05:44 > 0:05:48There is a big update coming on the first day of the game's
0:05:48 > 0:05:53release but I got a chance to play No Man's Sky for a couple of hours.
0:05:53 > 0:05:56Okay, I have woken up on a planet with a damaged spacecraft,
0:05:56 > 0:06:03I had to repair that ship by finding various minerals or mining minerals
0:06:03 > 0:06:06and finding the parts and making the parts required to take
0:06:06 > 0:06:08the ship off.
0:06:08 > 0:06:15It's the introduction to a lot of the game's exploration mechanic.
0:06:15 > 0:06:20So I have already met some unusual alien species.
0:06:20 > 0:06:22And all of the aliens in the game are generated,
0:06:22 > 0:06:29as everything else is, procedurally.
0:06:29 > 0:06:32So this is where the game starts in earnest.
0:06:32 > 0:06:35Explore an entire universe.
0:06:35 > 0:06:36I do want to go?
0:06:36 > 0:06:41Well, second star on the right and straight on till morning.
0:06:41 > 0:06:44There is a risk that people might find it boring,
0:06:44 > 0:06:48I think it will appeal to a certain type of gamer that likes the grind,
0:06:48 > 0:06:50the repetitive actions of going around and mining
0:06:50 > 0:06:54and getting resources in order to travel around.
0:06:54 > 0:06:57But I think once you've got past that initial
0:06:57 > 0:06:59maybe a couple of hours, you are going to find there
0:07:00 > 0:07:04is a massive universe to explore.
0:07:04 > 0:07:08When it is released next week fans will be able to decide
0:07:08 > 0:07:13for themselves if the wait for No Man's Sky has been worth it.
0:07:17 > 0:07:19It certainly looks really nice doesn't it?
0:07:19 > 0:07:22Yeah it is really pretty, when I was chatting to the game's
0:07:22 > 0:07:25lead designer, Sean Murray, he said there was a definite
0:07:25 > 0:07:27aesthetic they wanted to give the game.
0:07:27 > 0:07:30A lot of contemporary sci-fi games look really sort of gritty and dirty
0:07:30 > 0:07:34and he wanted this to be quite optimistic and bright and sunny.
0:07:34 > 0:07:37It does, to my mind it looks a bit like a 70s
0:07:37 > 0:07:39prog rock album cover.
0:07:39 > 0:07:42It does, is it any good?
0:07:42 > 0:07:45That is a difficult thing to say because I have
0:07:45 > 0:07:46played it for a few hours.
0:07:46 > 0:07:50It's so big, there is so much in there that you cannot really make
0:07:50 > 0:07:54that judgement unless you have committed lots, lots more hours.
0:07:54 > 0:07:56That's the thing, it's so big because the computers are designing
0:07:56 > 0:07:58everything, the planets and lifeforms, it's not
0:07:58 > 0:08:02as if some human has had to go and design everything meticulously.
0:08:02 > 0:08:04The beef I have with these procedural games,
0:08:04 > 0:08:09like Elite Dangerous which you know I play, is that although you can go
0:08:09 > 0:08:12anywhere and technically see anything the computers cannot
0:08:12 > 0:08:16generate storylines which are compelling so you find
0:08:16 > 0:08:18there is not actually much to do.
0:08:18 > 0:08:20It's quite an unforgiving universe, an unforgiving galaxy in these
0:08:20 > 0:08:24games, the player is just dumped into the game and told go ahead
0:08:24 > 0:08:26and make your own fun.
0:08:26 > 0:08:29It's a bit like going on holiday with your mum and dad
0:08:29 > 0:08:32when you are nine, you go to the beach and they are like,
0:08:32 > 0:08:33make your own fun.
0:08:33 > 0:08:35This is very similar to that.
0:08:35 > 0:08:37If people are expecting a single player game
0:08:37 > 0:08:40where they are led by the hand this is not that kind of experience,
0:08:40 > 0:08:43this is find stuff for yourself.
0:08:43 > 0:08:47OK Marc, see you in the sky.
0:08:49 > 0:08:52Medical treatment can be costly even in the rich parts of the world
0:08:52 > 0:08:55but in the developing parts of the world it can be prohibitive
0:08:55 > 0:08:58but there is a Silicon Valley start-up called D-Rev
0:08:58 > 0:09:00that is trying to address this healthcare gap
0:09:00 > 0:09:03by developing affordable technologies.
0:09:03 > 0:09:05Its first product was designed to treat jaundice which affects more
0:09:05 > 0:09:09than half of all newborns and its second effort
0:09:09 > 0:09:11was designed to help amputees who have lost a leg.
0:09:11 > 0:09:14Sumi Das has been finding out how these devices are helping
0:09:14 > 0:09:18the world's poorest patients.
0:09:19 > 0:09:22Their offices are modest but this team of engineers and designers
0:09:22 > 0:09:24in San Francisco is working on a bold goal.
0:09:24 > 0:09:27D-Rev exists to design and deliver quality healthcare products
0:09:27 > 0:09:33for underserved populations.
0:09:33 > 0:09:35Brilliance Pro is D-Rev's $400 phototherapy device.
0:09:35 > 0:09:37First launched in India it is an alternative
0:09:37 > 0:09:40to the $3000 units used to treat newborns with jaundice.
0:09:40 > 0:09:45You would see babies being treated under devices
0:09:45 > 0:09:47which have burned out bulbs, but also you would see
0:09:47 > 0:09:50multiple babies in one device which is not ideal
0:09:50 > 0:09:51to because you want to have the children
0:09:51 > 0:09:53separated for sterilisation.
0:09:53 > 0:09:56For affordability and durability D-Rev chose LEDs over
0:09:56 > 0:09:59compact fluorescents.
0:09:59 > 0:10:02They also ran optical modelling simulations.
0:10:02 > 0:10:05One of the things we have been able to use is use less LEDs,
0:10:05 > 0:10:08tightly control the wavelength and there are new lenses out
0:10:08 > 0:10:12so we can actually have a very even spread of light.
0:10:12 > 0:10:16If you are a doctor or nurse you might need to move this panel
0:10:16 > 0:10:18as you are caring for the infant.
0:10:18 > 0:10:20Of course that changes the intensity of the light
0:10:20 > 0:10:23but they accounted for that.
0:10:23 > 0:10:25They added accelerometers which detect the position
0:10:25 > 0:10:29of the LEDs so that each one automatically adjusts
0:10:29 > 0:10:33and the distribution of light is even across the baby's body.
0:10:33 > 0:10:36As with medicine it is crucial infants get the right dose of light
0:10:36 > 0:10:40therapy so a light meter was added.
0:10:40 > 0:10:44To date over 117,000 babies have been treated with Brilliance units.
0:10:44 > 0:10:5099,000 of those would not have retrieved any treatment at all.
0:10:50 > 0:10:53D-Rev's latest product is a knee joint.
0:10:53 > 0:10:59The ReMotion knee is a polycentric knee for above knee amputees.
0:10:59 > 0:11:01It's like a four bar mechanism which mimics your
0:11:01 > 0:11:03natural human gait.
0:11:03 > 0:11:06The previous option a single axis knee swings much like a door
0:11:06 > 0:11:08hinge and is less stable.
0:11:08 > 0:11:11The polycentric knee the centre of rotation moves so this man can
0:11:11 > 0:11:17continue working as a contractor and supporting his family.
0:11:17 > 0:11:21And this Indian teenager can keep up with his friends.
0:11:21 > 0:11:24In the US polycentric knees start at around $400.
0:11:24 > 0:11:28ReMotion sells for $80.
0:11:28 > 0:11:31Philanthropic grants help keep prices low.
0:11:31 > 0:11:36But D-Rev also credits it start-up tendency of working efficiently.
0:11:36 > 0:11:39Bug fixes included sharp corners and edges which didn't look
0:11:39 > 0:11:44natural underneath clothing and a distracting clicking sound.
0:11:44 > 0:11:47Fabric can fall smoothly over it and it has a rubber bumpers so it
0:11:47 > 0:11:51doesn't make as loud a noise.
0:11:51 > 0:11:55ReMotion has limitations, it is best suited for younger
0:11:55 > 0:11:59amputees since it's not as stable as other knees and the maximum
0:11:59 > 0:12:01weight for users is about 80 kilos.
0:12:01 > 0:12:06Still it's a good fit for many patients in Asia and Africa.
0:12:06 > 0:12:11It has a wide range in motion, much wider than most of the knees
0:12:11 > 0:12:14on the market especially in Western societies and the reason
0:12:14 > 0:12:19is that we saw with our users that they were squatting more
0:12:19 > 0:12:21or bending in prayer or kneeling.
0:12:21 > 0:12:24Many people need to ride a bike to get to and from work.
0:12:24 > 0:12:26Since the knee launched in December 2015 200 amputees have
0:12:26 > 0:12:29been fitted with them, that is 200 people who can go
0:12:29 > 0:12:35on working, learning, living - one step at a time.
0:12:41 > 0:12:43Hello and welcome to The Week in Tech.
0:12:43 > 0:12:47It was the week that the giant Chinese bus which drives
0:12:47 > 0:12:51over traffic went from concept to prototype.
0:12:51 > 0:12:56Moon Express became the first private company to get permission
0:12:56 > 0:12:59to land on the moon from the US government, whilst virgin
0:12:59 > 0:13:01Galactic SpaceShip Two received permission to take
0:13:01 > 0:13:02tourists into space.
0:13:02 > 0:13:05Instagram released its stories which look a lot like Snapchat
0:13:05 > 0:13:07stories, and Samsung showed off its Galaxy Note 7 fablet
0:13:07 > 0:13:11which includes an iris scanner so you can unlock it with your eyes.
0:13:11 > 0:13:15It was also the week we saw a video from MIT that you can
0:13:15 > 0:13:16reach out and touch.
0:13:16 > 0:13:17Which scientists said could have applications
0:13:17 > 0:13:18for games like Pokemon Go.
0:13:18 > 0:13:21The concept is called interactive dynamic video and uses cameras
0:13:21 > 0:13:23and algorithms to track almost invisible vibrations of objects
0:13:23 > 0:13:29to let them be interacted with.
0:13:29 > 0:13:32This augmented reality is getting pretty good.
0:13:32 > 0:13:35Speaking of Pokemon Go the game hit 100 million downloads this week
0:13:35 > 0:13:38and was also hit with the trespassing lawsuit
0:13:38 > 0:13:42from a man in New Jersey.
0:13:42 > 0:13:46He said at least five trainers had knocked on his door looking to catch
0:13:46 > 0:13:47pocket monsters in his garden.
0:13:47 > 0:13:50And finally if you ever wondered what a robot with a neural
0:13:50 > 0:13:54network would sing like, I know I have.
0:13:54 > 0:13:58Meet Alter, the latest humanoid robot from Japan has 42 pneumatic
0:13:58 > 0:14:00actuators and a central pattern generator which replicates
0:14:00 > 0:14:02neurons at Alter create its own patterns and react
0:14:03 > 0:14:19to its environment and sing.
0:14:19 > 0:14:22Now, every year in the middle of a desert thousands of hackers
0:14:22 > 0:14:27and security experts meet to talk shop.
0:14:27 > 0:14:32It is here in Las Vegas that the good hackers show the world
0:14:32 > 0:14:36what they can do and then the rest of us are left to worry about it.
0:14:36 > 0:14:39Dan Simmons has picked out a couple of highlights from the two
0:14:39 > 0:14:42conferences which happen here, in a second DEF CON but first,
0:14:42 > 0:14:46Black Hat.
0:14:46 > 0:14:53A hacked ATM just spewing out hundred dollar bills.
0:14:53 > 0:14:56Security gurus Rapid7 have shown how they can skim details from a chip
0:14:56 > 0:15:01and pin card from one cashpoint or pin pad machine and have this one
0:15:01 > 0:15:07believe it is being accessed with the same card.
0:15:07 > 0:15:12Behind that out of order sign is an android phone connected
0:15:12 > 0:15:14to the Internet and a microcontroller all fitted
0:15:14 > 0:15:19to the outside of this cash machine.
0:15:19 > 0:15:22Rapid7 isn't showing people how to do it, but they have told the ATM
0:15:22 > 0:15:28and card industries who we hope are working on a fix.
0:15:28 > 0:15:33As far as like the know how it's pretty advanced but we don't believe
0:15:33 > 0:15:36we are the only people looking at this, we absolutely believe
0:15:36 > 0:15:39that the existing gangs are already looking at how to overcome the lack
0:15:39 > 0:15:45of mag stripe in the US.
0:15:45 > 0:15:47And it doesn't end there, what about hacking peoples credit
0:15:47 > 0:15:49cards for example when they are out shopping?
0:15:49 > 0:15:51Patrick is from NCR, they have adapted this,
0:15:51 > 0:15:57this is a Raspberry Pi costing probably less than $50.
0:15:57 > 0:16:00It has been adapted and placed between what would be the card
0:16:00 > 0:16:03terminal where you put your credit card into and the payment management
0:16:03 > 0:16:17system which would be sort of behind the scenes.
0:16:17 > 0:16:20Pop the card in and the Raspberry Pi can be connected to maybe
0:16:20 > 0:16:22a supermarket terminal or it could capture your information
0:16:22 > 0:16:26when you are putting it into a pin pad which is connected to Wi-Fi
0:16:26 > 0:16:30at a restaurant, maybe something like that.
0:16:30 > 0:16:33I am being asked if I would like to accept the transaction
0:16:33 > 0:16:37amount of $10.30 I say yes and look at what happens to the Raspberry Pi.
0:16:37 > 0:16:40We already have the credit card number, it's a fake number
0:16:40 > 0:16:42you cannot use at home, sorry about that.
0:16:42 > 0:16:45I am going to put this pin number in, nothing unusual about that
0:16:45 > 0:16:48but it has asked me to put in the pin number again.
0:16:48 > 0:16:50I can do that again no problem.
0:16:50 > 0:16:53I might think I have put it in wrong or something like that.
0:16:53 > 0:16:56Now it has bypassed the encryption which was on this device and look
0:16:56 > 0:16:59at what has happened here on the Raspberry Pi.
0:16:59 > 0:17:01We have got the pin number for the card.
0:17:01 > 0:17:03We can go back and ask for the CVV2 number,
0:17:03 > 0:17:07the three digit number on the back of the card and once we have got
0:17:07 > 0:17:09all of that information what can we do?
0:17:09 > 0:17:14Now we can go shopping, go and get ourselves something nice.
0:17:14 > 0:17:16It's a brand-new attack, it is scalable and cheap
0:17:16 > 0:17:19and we expect the industry to respond to that.
0:17:19 > 0:17:23As a consumer the only thing we can tell you is just if you get
0:17:23 > 0:17:28requested to re-enter your pin number, don't do that.
0:17:28 > 0:17:33Over at the Paris Hotel DEF CON is where the bedroom hackers meet.
0:17:33 > 0:17:36Fred was 16 when he started and is now telling the world how
0:17:36 > 0:17:39he has found a way to hack into hundreds of solar panel arrays
0:17:39 > 0:17:41globally, through this small power management unit which came
0:17:42 > 0:17:48with his own home system.
0:17:48 > 0:17:52He could have even hacked into owners computers.
0:17:52 > 0:17:54Because I had full control over those devices I could deploy
0:17:54 > 0:17:57whatever software I wanted on them and because those devices
0:17:57 > 0:18:00were connected to your home network I could have easily put spyware to,
0:18:00 > 0:18:03for example, capture what websites you are visiting or see
0:18:03 > 0:18:15if you are home or not.
0:18:15 > 0:18:17The solar panel provider has since upgraded its security
0:18:17 > 0:18:20but there are plenty more hacks out there for all sorts of things.
0:18:20 > 0:18:33Some of which we will look at next week.
0:18:33 > 0:18:35Now, we talked earlier about massively open videogames
0:18:35 > 0:18:37on a humongous scale, the scale of a galaxy and how
0:18:37 > 0:18:41to keep all of your players interested when not all of them can
0:18:41 > 0:18:48play a significant part in the action.
0:18:48 > 0:18:52One solution is to hide a puzzle in the game which can then be taken
0:18:52 > 0:18:54out of the game for further discussion.
0:18:54 > 0:18:57That is something that has been driving the player community
0:18:57 > 0:19:02of space simulator Elite Dangerous absolutely batty recently.
0:19:02 > 0:19:05There has been so much heated and intelligent discussion as people
0:19:05 > 0:19:08try and decipher this puzzle.
0:19:08 > 0:19:11It's an image which has been found hidden inside strange
0:19:11 > 0:19:13space towns in the game.
0:19:13 > 0:19:16But what does it mean?
0:19:16 > 0:19:21And is it a message from aliens?
0:19:21 > 0:19:24After mysterious objects started turning up and disabling player's
0:19:24 > 0:19:26ships the community decided to examine more closely the strange
0:19:26 > 0:19:32sounds which were emitted.
0:19:32 > 0:19:34And this image turned up in the audio spectrogram.
0:19:34 > 0:19:36It's a technique which is well-known amongst audiophiles,
0:19:36 > 0:19:43take a picture and encode it as sound.
0:19:43 > 0:19:45Images have famously been hidden in several music tracks
0:19:45 > 0:19:52from the likes of the not at all creepy Aphex Twin.
0:19:52 > 0:20:01So if you ever hear a strange sound in a recording,
0:20:01 > 0:20:03you never know, it could be an image waiting to be discovered.
0:20:03 > 0:20:06The meaning of this one is still the subject of heated
0:20:06 > 0:20:13online debates and personally it's driving me nuts.
0:20:13 > 0:20:21Elite is one computer game from the 80s which has been given
0:20:21 > 0:20:25a new lease of life and next another one which has been techno shocked
0:20:25 > 0:20:33into the 21st century.
0:20:33 > 0:20:37Here comes LJ Rich.
0:20:37 > 0:20:46Some of these old games are just as playable
0:20:46 > 0:20:52as they were a few decades ago.
0:20:52 > 0:20:55But why settle for just dusting off the cartridges when you can go
0:20:55 > 0:20:56for a more immersive upgrade?
0:20:56 > 0:21:00This is a scrolling platform game where as you can see you keep
0:21:00 > 0:21:04playing and you keep going around.
0:21:04 > 0:21:08The best thing about this is soon I will be able to have a go.
0:21:08 > 0:21:11Bob Sumner, the creator of this project, is playing on a wireless
0:21:11 > 0:21:21controller following the action by walking around the room.
0:21:21 > 0:21:24360 degrees of gameplay certainly keeps the player on their toes,
0:21:24 > 0:21:26a very physical upgrade to additionally sedentary activity.
0:21:26 > 0:21:28After some persuasion Bob kindly hands me the controls.
0:21:28 > 0:21:29Come on, thank you.
0:21:29 > 0:21:29LAUGHTER.
0:21:29 > 0:21:32That is so fun, I had completely forgotten about anyone filming me,
0:21:32 > 0:21:34I just want to play this.
0:21:34 > 0:21:35I am on the door.
0:21:35 > 0:21:40Oh.
0:21:40 > 0:21:44The idea here was to take something like the Nintendo console which had
0:21:44 > 0:21:46this huge collective influence on an entire generation of people
0:21:46 > 0:21:49but it was always this sort of singular event, you played
0:21:49 > 0:21:51by yourself or maybe just a few people.
0:21:51 > 0:21:54So despite the fact that it influenced so many people you always
0:21:54 > 0:22:06experienced it sort of alone.
0:22:06 > 0:22:09It is still an old console but the video signal coming out
0:22:09 > 0:22:11is sent to a PC in the corner.
0:22:11 > 0:22:13That is were custom-made software stitches the video stream live,
0:22:13 > 0:22:15a bit like your phone in panorama mode.
0:22:15 > 0:22:17That stitched together video goes into the projection system
0:22:17 > 0:22:21which is then beamed onto the wall.
0:22:21 > 0:22:28You know there is something called game mechanics, the kind of core
0:22:28 > 0:22:30gameplay of the game is what makes it fun.
0:22:30 > 0:22:40And some of these classic games, they not only have good gameplay
0:22:40 > 0:22:43but they in fact really defined what good gameplay is.
0:22:43 > 0:22:45This was a team effort, some of these people helped design
0:22:45 > 0:22:47the wireless controllers, others the software,
0:22:47 > 0:22:50so it's good there is now a multiplayer mode for single player
0:22:50 > 0:22:52games otherwise I fear there would be a lot of sulking.
0:22:52 > 0:22:55This bit is also rather clever, the old controllers are plugged
0:22:55 > 0:22:56into specially designed hardware.
0:22:56 > 0:22:59The Nintendo box thinks there is only one person playing
0:22:59 > 0:23:05but actually there are eight of us taking turns.
0:23:05 > 0:23:08I have taken for granted the fact I am playing around a wall,
0:23:08 > 0:23:13I am immersed in the gameplay.
0:23:13 > 0:23:15The fact is this is completely wireless makes it worse.
0:23:15 > 0:23:16Goodbye productivity.
0:23:16 > 0:23:18Every 10 second the hardware switches control to the next
0:23:18 > 0:23:24controller - if you see your number on the wall you are the one playing.
0:23:24 > 0:23:27Control goes round in a circle which changes the dynamic
0:23:27 > 0:23:29of the original game mechanics, making it a much
0:23:29 > 0:23:33more collaborative experience.
0:23:33 > 0:23:35What it really added was the additional social element
0:23:35 > 0:23:36to the game.
0:23:36 > 0:23:38That was not present in the original concept.
0:23:38 > 0:23:41It created this new dynamic where you have strangers who have
0:23:41 > 0:23:43never spoken to one another immediately joined in camaraderie
0:23:43 > 0:23:55as they participate with a common goal to make progress in the game.
0:23:55 > 0:23:58That was LJ and Switzerland and that is it for this week.
0:23:58 > 0:24:01Next week we have much more from DEF CON, the massive underground hacking
0:24:01 > 0:24:04conference taking place at a secret location somewhere in the world.
0:24:04 > 0:24:05Las Vegas.
0:24:05 > 0:24:07And you can follow us on Twitter.
0:24:07 > 0:24:36Thank you for watching, we will see you soon.
0:24:36 > 0:24:36Good morning.
0:24:36 > 0:24:38It should be a lovely weekend for most of us.
0:24:38 > 0:24:40It will feel more like summer as well.
0:24:40 > 0:24:43Earlier we have this area of cloud, making the sunshine hazy.
