Actually, I worked in a lab at NIH this winter, and I ran across a group 
in NINDS that was working on a project very smilar to what you have 
suggested.  They were using a grid of (I think) iridium-coated gold wires 
implanted in the occipital cortex of macaques to simulate vision. At 
this point I don't think they are doing anything too fancy, in terms of 
higher visual functions, but it seemed like an encouraging start.  I met 
an electrical engineer who was working on the project, and they are 
slated to move to human subjects at some point this summer.  The 
engineer's name was Marty Bak, and he has at least one paper out on the subject.
