    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.

no fuckin clue how i got this in 81 characters
u/Qwitter

if you send a single pixel across the screen at this resolution (70) like fillRect(X+t,,1,1,1) you can see how the canvas has a smoothing effect by slowly pouring the alpha = 255 value between the pixels
