    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.

zensaiyuki: I found this trick for generating a 16 color palette: i*0x775511. i wonder if it can be made smaller in javascript.

u/iverjo

Neat. To begin with, you can replace 0x775511 with 7820561. Further, you can look into bit operations or modulo to truncate/slice the string
