Actually, someone's already doing this to produce a CGA display that's 3/4 X
3/4 inches (or so).  It hangs out in front of your face on an eyeglass-frame
type of thing (or headband?)  The image is superimposed on whatever you're
looking at, kinda like a heads-up display.  They use 200 red LEDs, and a
Piezo crystal to sweep horizontally.

I think it's called "Private Eye."
