    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.

Mostly an accident, but it looks cool anyway

u/DirtyDan

Pretty sure most dweets are, lol
u/artfarnaa

Every artist from every domain says same thing. Nothing great emerges without the author saying it was just an accident.

Not always true in creative coding/demoscene tbh
