There are a lot of wacky and psychedelic CA rules out there but SmoothLife by Stephan Rafler is different. Designed as a continuous version of Conway's Game of Life (using floating point numbers instead of integers), it supports a glider that can travel in any direction, as well as rotating pairs and strange elastic rope things. Don't miss the nice glider collision at around 3:12. Technical details can be found on the youtube page: SmoothLifeL
