I like the Multiverse one which is at the National Gallery of Art in NY. It seems like you are in space walking with shooting stars. From what I know, all his lights are LEDs but I could be wrong.
I found this video of an Artist who is programming lightings to make sculpture. Thought this would interest some of you.
