Frank Stephens from Connection Church in Canton, MI brings us this Superman fortress of solitude for their Samson series.
This set was all flat 1/2 inch styrofoam boards painted to look like crystals. Down along in front of the riser Frank curved 1/2 inch styrofoam boards with a heat gun to make them look round. He took a hot knife to make the cracks, taped wax paper behind the cracks, and stuck lights behind that. Everything is pretty much flat boards painted to look like crystals.
