They turn off the regular lights, and have strobes and black lights
instead. The kids love it. This was a birthday party for a 13 year
old, although they didn't have the whole room to themselves.

I, of course, had my camera in tow, with the 50mm 1.8, so I just had
to see what I could get (hand held, of course, no tripod with me). I
think the graininess adds to the atmosphere of the picture.
