I did some research in the area of artifical eyesight for a High
School report, and I seem to remember that a similar effect was 
achieved by attaching a teflon plate to the visual cortex along
the back of the brain.  Electrodes embedded in the teflon could
be switched on and off to create points of light in the person's 
visual field.

I seem to recall (this was a few years ago) that they expected to be
able to achieve resolutions similar to the resolution of a
scoreboard at a sports stadium.
