    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!

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 ?

Blimey!
u/robbyg

I would love to read a write-up of this some time!
u/BalintCsala

They aren't really complicated, they draw a circle of rectangles with a pseudo random displacement to make it seem more natural. The track is just a bunch of rectangles
u/richev

Maybe not complicated once you understand how it works, but sure seems complicated to me. As @robbyg said, I'd love a detailed write-up.

Takes a second to get going due to the limitations on how I could kick it off. The 184b version looks much better; I may post it when I'm satisfied with it.
