    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.

Brute-force dweet

Open in new tab and refresh to see random stuff
u/tomxor

I love the concept :D, it's a shame the results are so small. Maybe worth randomising the scale of some params beyond 1 also?
