    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.

quick test, why's this work?

u/deobfuscate

So that works and then I can't save two extra chars by excluding the ":"
u/danny@hille.dk

this is why it works: https://developer.mozilla.org/en-US/docs/Web…
u/danny@hille.dk

it is the same as writing: if(x)x.fillRect(1,23,456,789)
