    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.

Wow! Too bad it doesn't reset, but this looks incredible!

As you can see, the server might go down a bit soon. Also, it went down by mistake for a minute or so just now. I hope no-one lost a dweet! :( Sorry

A demonstration that abs(sin(x))**.9 is a good compact approximation of bouncing.

u/lionleaf

Nice! that's a useful trick! Why not just abs(sin(x)) though?
u/magna

**.9 compresses the curve and makes the restitution look more realistic.
