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." ----------------------------------------------------- Gordon S. Hlavenka cgordon@vpnet.chi.il.us Disclaimer: Yeah, I said it. So what?
