The Laser-Galaxy projector is designed to explore “old-school” optical laser effects. When many people first got their hands on a laser in the 70’s, one of the first things they did was to shine it through pieces of clear, rippled, glass on to a wall or ceiling. The effect was great!
Many early laser shows, especially the popular Laserium planetarium shows, had whole banks of these types of effects, and used them extensively throught their shows. In the last decade, however, more exploration and work has been concentrated upon precisely computer controlled graphics and scanned beam effects through smoke.
