    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.

This is the most realistic dweet I ever seen!
u/yonatan

Thanks. I have a much nicer (and longer) version in flash at http://wa.zozuar.org/code.php?c=2HBv (click the "get flash" gif for chrome to activate it)
u/sigveseb

Fantastic! Looking back and comparing with the old water/ocean dweets from the early days of dwitter, we sure have come a long way since then!
u/jmpp

This is dope! I'm new to all these crushing techniques and wonder how did you get the Asian sign version of your algo ?
