I tend to do stuff that looks sort of neat at the time, but invariably I come to my senses and realize the tremendous worthlessness of it. Usually this work goes into the round filing cabinet next to my desk, but one day I discovered a particularly unintelligible piece surviving in a hidden corner on my hard drive. So I decided to start collecting these things here, along with other unpublished stuff. The list is currently small, but I expect it to grow quickly. For amusement purposes only.
