Dorking around on the Hell-Tar

Last nite I finally got around to taking some videos of the Hell-Tar, which I modded months ago. The sounds are pretty intense and may not be suitable for children. The design includes a 555 LFO with various opto sensors. There are touch sensors in the form of staples in the top of the body. The chickenhead controls the main pitch and all the other switches do various stuff, but I don't remember what. So this is just noodling.
