A continuous cellular automaton where every cell becomes an activation of the convolution of the grid with a ring-shaped kernel, plus a global oscillating bias.
One equation, x' = (1 - a) x + a f(K * x + h(t)), covers Turing patterns, SmoothLife-style automata and Lenia, and the analysis panel below the canvas shows the linear-stability prediction live.
Started as a 2023 Colab notebook. Click any label or ? for an explanation, try the presets, and use the sweep to map regimes; the URL hash records every parameter, so a link reproduces an experiment exactly. Needs WebGL2.
