    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.

JavaScript is awesome. $.$(..._($._)._(_.$)) is the only code responsible for drawing.

u/KilledByAPixel

Cool, can you explain it? You don't need the ._ after prototype
u/username

How would you do it without it?
u/KilledByAPixel

Oh my bad, I deleted that after it was already created.
