Great stuff, everyone! I really do love seeing what people come up with.... I haven't played with the GI and caustics much in C yet, but I will, soon.... It's really beautiful what the new renderer does. And Curious Labs is using a dongle now? Who knew? I thought those went out with AfterEffects 5.0.... Hope everyone's having fun with this.... If anybody has another 15 minute challenge idea, let's go; I always think they're fun and a great learning experience.... - Dex
