@Zacham: LOL, yeahhhhhhh, about that.... the video never got made, lol. It's seen some minor adjustments since I built it and it works better now. I'll get some more pictures later on and try to explain it a little better. I'm going to be rebuilding one, though, soon. Might want to wait until then since it'll have adjustments that I think are beneficial, lol.
@Wireman: I just hung a piece of felt behind the plants and used a flashlight to shine at the felt from behind. No other light source. It's pretty fun. I have lots more pictures, I will try to throw them up tonight some time.
