For the lazy game designer... Just add chip tunes and a player :D

Awesome!

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

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.
