    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.

u/iverjo

Interesting that you used the "with" operator
u/sfz

with(Math) could be pretty useful
u/gabrielsroka

@iverjo, yeah, not recommended, and may not be supported in future versions of JS, but i needed a few extra bytes
