The Laserium is a laser show put to music and shown at a planetarium. They pick a theme like Pink Floyd's Dark Side of the Moon and make a laser show around it. You could see a Laserium show at the Morrison Planetarium in San Francisco, back in the 70's
Dude, did you check out the Pink Floyd Laserium show last night? It was outta this world.
