Yes this is undergoing clinical tests right now for FDA approval.

Todays issue with prosthetics aren't from the motors or servos. It is actually transmitting what the motors and servos should do and giving feedback. One could use the nerve endings to control them, but you tell me how?

tell a patient to think about moving his/her arm
record nerve activity
repeat several thousand times
then program a microchip to read the correct nerve activity and give instructions to the motors.

also a servo is a motor.

the current research is about how to eliminate the computer and wire the motor controller into the arm nerves themselves.

Does anyone know if the nerves that go to the missing limb can deteriorate?

it depends on how far down the what's-left-of-arm the blood vessels still work.

I want to do this Although, $5,000 is a bit pricey. If I had the cash I would totally be all over this.

You'd be willing to pay people to shoot lasers in your eyes simply to change the colour of your eyes?

inb4 people use that to draw little thing on their eyes

Okay, now that would actually be kind of cool and maybe worth it.

>doctor claims he can change the color of your iris

It's interesting, but all I can think of is doctor Mengele's experiments, which would somewhat deter me from ever wanting the procedure.
That, and I already have blue eyes.

Nazis did it, let's never follow up on their research.

That would be pretty cool, but that could be extremely dangerous couldn't it?

Exactly my concern. Although laser eye surgery is pretty safe, any kind of surgery has a risk. Is it really worth the risk of turning blind to change something minor as eye color?

In other news, diamonds aren't forever and slowly change back in to graphite at room temperature/pressure.

You are saying cosmetic surgery isn't worth the risk? Not much risk in it. Just a few horror stories of the few cases things go bad in. Not that I personally want to change anything, but if someone wants to, I don't see why they shouldn't be able to.

I'm not saying cosmetic surgery isn't worth the risk, I'm saying this particular type isn't worth the risk.

Well isn't that what they make color contacts for anyways?

AWKWARD ZOMBIE
