Cellular automata beat layers
CA looks can inject new geometry on beat instead of wiping the grid. Layer hues cycle per inject — a practical CA beat visual on four-on-the-floor tests.
TekDetek is not completely free. Swipe CA looks and edit for free. Clean unlimited export and adding CA on the desktop graph is Pro.
