    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.

Test using t as the y axis, like a scan line

Dwitter seems cool, heres something I made to try it out

Its in no way fully minimized, lol. Just shrunk it to fit within 140.
