I've been lurking here for a while, but now I have a question that I need help on! I'm (unofficially) in charge of my schools lighting and sound crew. Recently I was approached by the person in charge of the decorations for the Christmas choir and band concert about different things we can and can't do. I've had the idea for a while about projecting the schools logo onto the curtain behind the risers the choirs gather on. They liked the idea. Here's where I need help. What equipment do we need to get a gobo to work with a ETC Source Four Jr? This will be the second year with the Source Fours, so we don't have any accessories for them. Thanks!
