    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.

This uses a modified version of DCT. All data is in 2 magic strings. To create your own: https://pastebin.com/zEH5aH1R copy this to a dweet draft, draw, get your own magic strings.
