Here is somthing kind of cool. If you have a Cyc in the back of your stage here is a cool way to make things seem to float (Sort of). All you have to do is get some extra cyc materal or some old pieces of white scrim. Build some platforms on stage, focus strip lights on your cyc. Staple the old scrim pieces onto the front of your platforms and place a strip light behind them. If you leg the platforms correctly you can get very few shadows directly on the scrim materal form behind giving you a good solid color. This makes a great effect for concerts and things where you need a little extra light, you can change the color of the platforms and the cyc for a cool effect or you can make them the same color, which if done correctly can make the bottoms of the platforms blend into the cyc behind giving you a floating effect.
