Solid state RGB lasers against XY scanning mirrors. Beams modulated rather than filtered. The only limits on resolution will be the modulation bandwidth and the X scanning speed. I've been waiting for someone to make this since 1981.
I can hardly wait to hack this unit. I'll add holes to the case allowing much higher powered external lasers, as well as controls for attenuating the scanner deflection if it doesn't already have the latter.
Video onto clouds, vacant billboards, warehouse walls, and best of all: revive that neighborhood drive-in theater which has been sitting there vacant for decades. Just add a Ramsey FM modulator kit, and invite your entire town to the movies.
And how come all the fun is illegal nowadays? Our parents never had that problem!
