one other thing i've been thinking about...

so, microcontrollers are cheap. and there's a growing user-base of easily-accessible microcontroller related stuff, with the arduino etc.

there ae a bunch of people who have prosthetics. and there's a lot of kids coming back from overseas missing limbs. some of these people have to be nerds.

why am i not yet hearing about people doing customized things involving prosthetic limbs and electronics? i mean, outside of the MIT leg lab.

i assume it'll happen eventually. i'm just surprised it hasn't happened already.
