The electroptics whizzes at Zenith tried this, using Bragg cells as modulators/deflectors, and three tuned lasers for the colors. Unviewable. The problem is the scintillations typical of laser light (interference patterns, actually, and did you realize that you can determine if you are farsighted or nearsighted by the way the scintillations move when you move your head?). They never did find a good way of eliminating the scintillation effects, and had to abandon the project. -- ---------------- "... if the church put in half the time on covetousness Mike Farren that it does on lust, this would be a better world ..." hoptoad!farren Garrison Keillor, "Lake Wobegon Days"
