    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.

If you change some of the parameters, you could set it to 4 colors, but i didnt need to lol
u/rodrigo.siqueira

You can save 2 characters if you remove 2 first lines of code and start with: t?x.fillRect(y++%16..... and end with: .../2):(y=0,c.width=40)
