I stumbled across this
and for the life of me can not remember who has the blind and deaf wife [I know there was something in his Bio about it, but I can't seem to find it]. I just read a post of his in the last coupla days and i can't figure out where it was/is. I was hoping to get this to him. Pretty neat stuff. Google for intraocular retinal prosthesis
Anyway I know some of you know who I'm talking about.
