 Cool idea...Is the result similar to lissajous, or something else? I'm 
guessing this guy wants to do a bit more than oscilloscope stuff though, like 
manipulating various video components individually maybe (luminance, 
chrominance, colors, signal mixing etc..) I've seen some amazing stuff done 
at noise shows by video artists but I'm not sure exactly what gear they were 
using. I know popular electronics had an article some time ago on building a 
video effects box that seemed pretty good, I'll look through my back issues 
and scan it if anybody wants it.
