Now on BBC News, it's time for Click.

This week: 3-D printed legs.

Careless cash machines.

And aliens.

Lots and lots of aliens.

I've always wanted to go into space.

Hey, I'm a future boy, always have been.

And I'm lucky to be living in a time when the beauty of the universe

is being brought to life.

From earth you can now photograph amazing skies, if you know

what you are doing.

Which the entrants for this years Insight Astronomy Photographer

of the Year Awards clearly do.

Actually going into space though is still a pipe dream for me.

Unless you count shoddy TV effects like this.

Oh, and videogames of course.

If you count video games I have already been across the galaxy.

There are a number of games around now you see which let you go

absolutely anywhere.

The question is, would you want to?

Marc Cieslak has been to meet the makers of what is quite possibly

the most universal game yet.

I grew up reading sci-fi books, looking at the covers,

when I close my eyes and think of science-fiction I think of that.

I think of a lone astronaut stood on a desolate planet with a couple

of other huge planets hanging in the horizon and these kind

of wild and crazy worlds.

No Man's Sky is a space exploration game.

It encourages the player to discover strange new worlds and lifeforms.

There is trading and commerce.

As well as allowing people to blow stuff up.

All in a playable universe which is so big the games

own designers predict most players won't even experience one percent

of the worlds the game has to offer.

It might be a game with a gigantic exotic alien universe to explore

but it has been created in these tiny offices beneath a taxi

company in Guildford.

Indie games company Hello Games consists of just 11 people.

The team's previous credits include fun stunt riding game Joe Danger.

No Man's Sky is the brainchild of Sean Murray, who,

along with this tiny team, has found a clever way to fashion

this gigantic game and it's all thanks to maths.

We are trying to build an entire universe and we can't build that

by hand, normally when you make a game it's a series of levels

and some artist or designer has built every one of those

levels piece by piece, arranged all the furniture

and everything like that.

But we want to build something of a huge, huge scale.

We just can't do that on our own, we're this tiny indie team,

so what we do is we use the computer to build it.

We create a bunch of rules, a set of maths and the computer runs that,

we effectively teach the computer the rules that we think we need

to build a universe.

The computer goes off and generates it, builds it for you.

This process is called procedural generation and it is how everything

in the game is made.

From the planets to the aliens to the ships to the smallest

blade of grass.

It's not random, those rules are there for a reason.

What we are trying to do is create a set of rules and formula

that we feel creates a nice looking universe.

The size of the universe is incredibly big.

There are a lot of planets, if you were to visit them

all there would be 18 Quintilian which is this huge number,

it's like 2 to the power of 64.

It's a hard number to comprehend.

The way I normally say it is like if you were to discover

a planet or a planet was to be discovered in No Man's Sky every

second it would take about 500 billion years for them

all to be discovered.

With its first reveal back at E3 in 2014 this game generated

a considerable amount of anticipation as well as

hype amongst gamers.

I'm feeling a lot of emotions right now.

However some of this attention hasn't all been positive.

One gamer claims to have purchased a copy of the game ahead

of release for ?1200 via eBay.

After posting clips online he claimed it's possible to reach

the centre of the game's universe in just 30 hours.

This is a task developers have suggested would actually take

about 100 hours of playtime.

Sean Murray has implored fans to avoid these online spoilers.

There is a big update coming on the first day of the game's

release but I got a chance to play No Man's Sky for a couple of hours.

Okay, I have woken up on a planet with a damaged spacecraft,

I had to repair that ship by finding various minerals or mining minerals

and finding the parts and making the parts required to take

the ship off.

It's the introduction to a lot of the game's exploration mechanic.

So I have already met some unusual alien species.

And all of the aliens in the game are generated,

as everything else is, procedurally.

So this is where the game starts in earnest.

Explore an entire universe.

I do want to go?

Well, second star on the right and straight on till morning.

There is a risk that people might find it boring,

I think it will appeal to a certain type of gamer that likes the grind,

the repetitive actions of going around and mining

and getting resources in order to travel around.

But I think once you've got past that initial

maybe a couple of hours, you are going to find there

is a massive universe to explore.

When it is released next week fans will be able to decide

for themselves if the wait for No Man's Sky has been worth it.

It certainly looks really nice doesn't it?

Yeah it is really pretty, when I was chatting to the game's

lead designer, Sean Murray, he said there was a definite

aesthetic they wanted to give the game.

A lot of contemporary sci-fi games look really sort of gritty and dirty

and he wanted this to be quite optimistic and bright and sunny.

It does, to my mind it looks a bit like a 70s

prog rock album cover.

It does, is it any good?

That is a difficult thing to say because I have

played it for a few hours.

It's so big, there is so much in there that you cannot really make

that judgement unless you have committed lots, lots more hours.

That's the thing, it's so big because the computers are designing

everything, the planets and lifeforms, it's not

as if some human has had to go and design everything meticulously.

The beef I have with these procedural games,

like Elite Dangerous which you know I play, is that although you can go

anywhere and technically see anything the computers cannot

generate storylines which are compelling so you find

there is not actually much to do.

It's quite an unforgiving universe, an unforgiving galaxy in these

games, the player is just dumped into the game and told go ahead

and make your own fun.

It's a bit like going on holiday with your mum and dad

when you are nine, you go to the beach and they are like,

make your own fun.

This is very similar to that.

If people are expecting a single player game

where they are led by the hand this is not that kind of experience,

this is find stuff for yourself.

OK Marc, see you in the sky.

Medical treatment can be costly even in the rich parts of the world

but in the developing parts of the world it can be prohibitive

but there is a Silicon Valley start-up called D-Rev

that is trying to address this healthcare gap

by developing affordable technologies.

Its first product was designed to treat jaundice which affects more

than half of all newborns and its second effort

was designed to help amputees who have lost a leg.

Sumi Das has been finding out how these devices are helping

the world's poorest patients.

Their offices are modest but this team of engineers and designers

in San Francisco is working on a bold goal.

D-Rev exists to design and deliver quality healthcare products

for underserved populations.

Brilliance Pro is D-Rev's $400 phototherapy device.

First launched in India it is an alternative

to the $3000 units used to treat newborns with jaundice.

You would see babies being treated under devices

which have burned out bulbs, but also you would see

multiple babies in one device which is not ideal

to because you want to have the children

separated for sterilisation.

For affordability and durability D-Rev chose LEDs over

compact fluorescents.

They also ran optical modelling simulations.

One of the things we have been able to use is use less LEDs,

tightly control the wavelength and there are new lenses out

so we can actually have a very even spread of light.

If you are a doctor or nurse you might need to move this panel

as you are caring for the infant.

Of course that changes the intensity of the light

but they accounted for that.

They added accelerometers which detect the position

of the LEDs so that each one automatically adjusts

and the distribution of light is even across the baby's body.

As with medicine it is crucial infants get the right dose of light

therapy so a light meter was added.

To date over 117,000 babies have been treated with Brilliance units.

99,000 of those would not have retrieved any treatment at all.

D-Rev's latest product is a knee joint.

The ReMotion knee is a polycentric knee for above knee amputees.

It's like a four bar mechanism which mimics your

natural human gait.

The previous option a single axis knee swings much like a door

hinge and is less stable.

The polycentric knee the centre of rotation moves so this man can

continue working as a contractor and supporting his family.

And this Indian teenager can keep up with his friends.

In the US polycentric knees start at around $400.

ReMotion sells for $80.

Philanthropic grants help keep prices low.

But D-Rev also credits it start-up tendency of working efficiently.

Bug fixes included sharp corners and edges which didn't look

natural underneath clothing and a distracting clicking sound.

Fabric can fall smoothly over it and it has a rubber bumpers so it

doesn't make as loud a noise.

ReMotion has limitations, it is best suited for younger

amputees since it's not as stable as other knees and the maximum

weight for users is about 80 kilos.

Still it's a good fit for many patients in Asia and Africa.

It has a wide range in motion, much wider than most of the knees

on the market especially in Western societies and the reason

is that we saw with our users that they were squatting more

or bending in prayer or kneeling.

Many people need to ride a bike to get to and from work.

Since the knee launched in December 2015 200 amputees have

been fitted with them, that is 200 people who can go

on working, learning, living - one step at a time.

Hello and welcome to The Week in Tech.

It was the week that the giant Chinese bus which drives

over traffic went from concept to prototype.

Moon Express became the first private company to get permission

to land on the moon from the US government, whilst virgin

Galactic SpaceShip Two received permission to take

tourists into space.

Instagram released its stories which look a lot like Snapchat

stories, and Samsung showed off its Galaxy Note 7 fablet

which includes an iris scanner so you can unlock it with your eyes.

It was also the week we saw a video from MIT that you can

reach out and touch.

Which scientists said could have applications

for games like Pokemon Go.

The concept is called interactive dynamic video and uses cameras

and algorithms to track almost invisible vibrations of objects

to let them be interacted with.

This augmented reality is getting pretty good.

Speaking of Pokemon Go the game hit 100 million downloads this week

and was also hit with the trespassing lawsuit

from a man in New Jersey.

He said at least five trainers had knocked on his door looking to catch

pocket monsters in his garden.

And finally if you ever wondered what a robot with a neural

network would sing like, I know I have.

Meet Alter, the latest humanoid robot from Japan has 42 pneumatic

actuators and a central pattern generator which replicates

neurons at Alter create its own patterns and react

to its environment and sing.

Now, every year in the middle of a desert thousands of hackers

and security experts meet to talk shop.
