My private experements just for fun. I designed some original rules of [cellular automata](https://en.wikipedia.org/wiki/Cellular_automaton) and built a sort of Oekaki BBS based on them. Users can doodle on canvas just like the Paint app on Windows, and by following the rules of cellular automata, pixels on canvas dynamically evolves into unexpected patterns.

Users also can share their canvas. The number of shares is more than 2,000 in 2 years. Some people started to try a new way of playing with it and some funny memes have been born beyond my expectations.

It also picked by [Chrome Experiments](https://www.chromeexperiments.com/experiment/fuse).
