    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.

Save a char by moving the fillRect call into the loop body to avoid ;
u/yonatan

you're right!
u/keithclark

I love this!
u/yonatan

it's also better to use rect height for the "alpha", avoids the jagged edges on the right. for(i=c.width=99;i--;)for(j=56;j--;)x.fillRect(i,j,1,(S(j*j+i/j-t*7)+C(j**5-i/j*6+t)**3)*j/99)

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.
