What happens when half a cellular automaton runs Conway's Game of Life and the other half runs a rolling version of Rule 30 pushing chaos across the border? https://www.youtube.com/watch?v=IK7nBOLYzdE, via https://news.ycombinator.com/item?id=22723884

I wish I could see a larger scale of time and space to get an idea of how far the effects penetrate. If the boundary emitted gliders at a constant rate they'd collide far away in a form of ballistic annihilation but the boundary junk and glider-collision junk makes it more complicated.

@freakazoid Yes. The number of possible rules, \(S^{S^{(2n+1)^d}}\), looks like it grows enormously quickly, but when \(S=2\) (two states), \(n=1\) (neighbors are only one step away), and \(d=1\) (Rule 30 is a one-dimensional rule), its actual value (256) isn't so bad.

It does seem odd to me to encode what is inherently a binary value in decimal, though.

Federated Republic of Sean@freakazoid@retro.social@11011110 The fact that "30" completely describes the ruleset of the bottom CA (in the context of a 1d binary CA with a contiguous 3-cell neighborhood) blows my mind.
