    I enjoyed this and it warmed my heart a bit to see 4m views for some math animations. Maybe popular on r/trees or something :)

    I was curious what they used to generate the graphic's and it's their own tool:

    It reminds me of the billiards segment in Donald in Mathmagic Land[0]. I absolutely adored it as a kid.

    The emergent patterns are... stunning. Especially the ones around 2m35s https://www.youtube.com/watch?v=kL9BTbIGxLg&t=2m35s

    Wow this is stunningly beautiful and extremely cool. And I learned something I had never heard about.

    BRB going to go make hyperbolic outer billards art

More from this day
