> From the software point of view, perhaps laser projection TV technology might be better suited to what you want to achieve.
Laser projection TV is boring. I've got one, and it's more or less the same as any other tv. Hook up an HDMI and go. It doesn't give you a laser light show, even if it is technically laser, light, and a show. Technically they're pretty boring too, they're lcd or dlp projector with a laser instead of an incandescent light source.
The OP clearly wants an x-y servo mirror / galvonometer setup plus some way to modulate the laser. Some people experiment with scanning mirrors in one dimension, but then you end up with a rasterized display and not the smooth curves or a true laser show.
