Grant Sanderson's site, 3Blue1Brown, has an interesting video about colliding blocks generating the digits of Pi: 6Xh-jhDJ4 .

For an explanation of why this works, see: https://www.youtube.com/watch?v=jsYwFizhncE

He has another video showing another dynamic system using this principle of converting problems of dynamics to problems of geometry: https://www.youtube.com/watch?v=brU5yLm9DZM .
