    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.

Explorations through unknown structures

u/vain

Wow, brilliant. With a little imagination you can recognize a skull face. Did the formula come about by chance or is it based on some known algorithm?
u/rodrigo.siqueira

u/vain , you can click 'remix of...' enough times to see where the formula comes from. It originates from Saturn by u/tomxor
u/rodrigo.siqueira

(t*i/b&1) could be shortened to (i*b&1) and it is a random binary number "0" or "1". The variables a and b evolve over time in a discrete dynamical system, producing oscillatory, chaotic, and fractal-like behavior.
