    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

sierpinski triangle :D
u/xem

It'd be nice to have a blog post explaining it :) (please?)
u/trupples

I didn't look much into it but it might have to do with a thing I read about once where if you have a point that "walks" half the distance towards a random corner of a triangle you'll end up drawing a sierpinski triangle sorta like you can see in https://www.dwitter.net/d/5097
u/trupples

And according to http://distrustsimplicity.net/articles/sierp… if you were to use 4 points instead of 3 you'd get a tetrahedron like in this dweet. Fascinating stuff
