These are now a common Indeed, the gadget is called a Scanner, popular makes are Roboscan and Robozap, they consist of a color wheel (gobi), a pattern gobi and a shutter along with an Xenon MSR1200 lamp (1.2kW). The scanners are chained together in a bus network configuration, the whole lot is run by a PC (Roboscan 2032 controller is a PC AT) A top of the range Roboscan costs approx 8000 dollars. Something that looks more like a laser is called an Emulator, they are made by a nevada company, whos name escapes me at the moment. Anyone here built any disco lighting effects? I'd like to hear from you.
