    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.

Consider using properly formatted HSL if you have the characters to spare - these all show up as 100% black on iOS Safari!

oh would you look at that, now i can say i've made a dweet! (the performance isn't very good from what i've experienced, but the visual turned out well, so make of it what you will)
