    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.

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.

u/KilledByAPixel

there is nothing to see! maybe you meant to not clear the canvas? try removing c.width|=
u/SockTaters

It's a little faint, but I can see it breathing
u/magna

What browser y'all using? I see it with chrome both on mac and win.
u/tomxor

I can see it on Linux using Firefox@30 FPS and Chrome@15 FPS. I suspect on a phone it's going to be single digits with Chrome so it's going to take a whlie to appear.
u/joeytwiddle

I'm using Firepants on a BlackberryPi in 2076, looks fine here
