Sisyphus is a kinetic sculpture that rolls a ball through sand, forever creating and erasing beautiful patterns. Sisyphus is a kinetic art piece: it is an instrument. As a musical instrument plays songs, Sisyphus plays paths. This app provides a coding interface for creating unique and interesting algorithmic sand art patterns. Create and save your code using drag and drop blocks, JavaScript, or Python. It includes a tutorial to learn how, Challenges to test yourself, and Examples showing some code concepts. Connect to your Sisyphus to Print directly onto the sand, and save for later playback.
