Hey! So I am the lighting guy at a church and we are prepping for Easter. Our creative guys came to me and asked me to think about this and am not coming up with much of anything. Here is what he gave me. The back drop is a foresty kind of backdrop with a few other trees on stage as well. What he also wants is for there to be giant cross in the midst of all that but it is almost invisible until hit with light correctly at a certain time in the service. The premise of it is the cross is the light in a dark world world. They want it to be almost bright enough that make people look away but not quite. He used words like iridescent or prism. I was thinking well maybe just make one out of prisms and shoot light at it from different angles but not able to find a prism that is bigger than 1ft. So do you guys have any ideas? I'm stuck....
