Sisyphus I & II were the first two iterations of the Sisyphus series (see Sisyphus page for more general information). Here I include some details of the development process:
After some preliminary tests, I decided to build a prototype, Sisyphus I, which I then used to test some simple spiraling designs. The results were even more exciting than I could have predicted.
Following Sisyphus I's success, I built Sisyphus II for an art show at the Science Museum of Minnesota. This time I decided to use polar coordinates and increase the size to 5 feet diameter.
