Owledge Posted June 25, 2013 I was wondering whether any of you know a non-complicated way to decorate a room with more or less random rainbow-colored light. At first I thought prism, but even sunlight seems to be an insufficient light source, and I don't want to build something. Is there some light source driven lighting solution for getting some rainbows projected onto a room's walls/ceiling? Can be more or less random, I'm not picky, since a brief WWW search didn't yield any result. Share this post Link to post Share on other sites
