    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.

Very useful shortcuts, I'll have to use them in future. ...I'm thinking like a C programmer - in the C standard the order in which arguments are evaluated is unspecified; apparently the ES standard strictly defines order-of eval to be the intuitive left-to-right order. Good to know!
u/micahcowan

Ha, it feels "wrong" to set fillStyle 9 times in a row. But a great way to eliminate that last little character!

When you're out of characters you can shave "legally", you have to start compromising and enter the "wrong" and/or "meh, it's just a good approximation" territory :)
u/magna

Like Math.PI * 2 === 7
u/micahcowan

Heh, totally. :D
u/pythech

hack to save 2 chars: x.fillStyle=R(-D*9e7)
u/pythech

I guess that's "meh" territory
u/magna

Turns out approximations of pi are fine if you're not multiplying with your bad approximation of pi.
