Thanks for all of the great comments!

The drum was rather disappointing. It just kind of rattled. No real drum noise, hopefully it was broken.

The technicolor, was a dark room where there was a new age music playing, a video projector hooked up to a video camer (or webcam) and a bunch of IR LEDs. I assume there was a computer somewhere behind the scenes. Not only was the picture going through patterns but it was actually affected by what the people in the room where doing (I won't call it dancing).

We really did have a lot of fun. Most of mine fun came from watching the kids. I didn't get any comments from anybody at the museum, I didn't even notice any looks. We ate lunch in a bar down the street before hand and I definitely got alot of looks in there. No real comments. Then again when I am with the kids I don't my attention is often on them not people around us.
