I just stumbled across AtmosFX and it's something I'm considering giving a try. I already own an inexpensive no name projector that I've used for sports watching in the garage and think it might work well enough to project the effects. I'm pretty sure some of you have experience with AtmosFX so can anyone recommend what to use as screen material that I could purchase from a local store? I'm interested in the Creepy Clowns decorations. If anyone has pics of your DIY screen can you please post it so I can get some ideas. And advice and help would be much appreciated.
