    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.

A worm? A chinese dragon? For sure the ugliest code I ever wrote

u/BuRRak

Ugly code is the key in code golfing, isn't it?
u/sirbo

it's the key for running code :)
u/zanella

You can replace t<1 with !t. Yay, code golf!
