    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.

Oh, why do you use kanji characters as variables?
u/AnnanFay

The kanji are so I don't accidentally redefine a variable which something uses. For example there's code which does t||(_=c.width) so if I use _ it would break the code. It will break stuff which uses these kanji, but right now this is the only dweet using them.
u/fujimotos

Nice. I didn't know that they are valid variable names...
