200mW 650nm Spiro

Video of a red spiro I threw together in about 20 minutes.No planning involved just a couple of DC motors salvaged from cd-roms.Each wired with it's own (inadequate...way too touchy) pot with some diy mirrors made from a cd (speed control only with no reversing).I don't think it turned out too bad considering it was made on a whim just to convey the principle to some non-technical friends.:twak:
