This is the classic big-city highly-decorated cathedral, but with a twist. They have a sound, light, and laser show, called Aura, that makes great use of the space. It's like if Pink Floyd went to church. It's about $19, and you can (and probably should) book tickets online.
You can also visit the space during the week and take pictures with no show. If you want some great pictures, this is actually what you should do. While you're in the church just before the show, you can take pictures but the lighting isn't really conducive then.
