Especially an older one that you don't really care for anymore? I was thinking of dumping one on the inside of a car tire with a flashlight taped to it .... I wonder what that would look like? Or how about inside a piano looking down the row of keys as you played something? How about taped to the end of a drum stick and then play some Deep Purple? Or how about one taped to the fan blade in your car? That might be kind of cool. (My brother and I actually did tape a Bic pen for a Bic torture test on a truck fan blade and it worked out swell!) Any other ideas?
