    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.

I had a RGB CRT setup, but I hadn't been able to fit any interesting patterns: d/7512
u/tomxor

I had a look at yours magna, they are true crt, much more realistic i think. The scan lines on this are just a sideeffect I exploited and it was easy to add colour distortion in the R().
u/magna

Here we go: d/10843
u/C010011012

is it a cellular automata?
u/tomxor

Yes and no, it's a fractal n=T(0|(i/w+f^f-i/w)/(t**.7+6)) which is just a more elaborate variation of serpinsky triangles to produce more interesting patterns. Some fractals are automata, but not all automata are fractals, see here: https://en.wikipedia.org/wiki/Rule_90
u/tomxor

The implication is serpinsky triangles are computationally reducable, meaning it does not have to be computed in the same way as a cellular automata i.e state can be computed at step t directly without traversing intermidiate steps.
