I wonder how well one of these things would mount to a fan blade in a box fan, or something similar.
About 10 years ago a friend showed me a small black box, about 12" square, and inside was a spinning armeture with red and green LEDs on it. It had an internal mic with adjustable sensitivity and pulsated to the beat of the music. As the arm spun, the LEDs would change patterns and make different shapes and images. Ever since then I've been on the lookout for something like it. I work as a DJ for school dances, company parties and such, and if I could find a product like this, I'd be happy as a pig in slop.
Cheers!
