Cellular automata video on webcam
TekDetek turns your feed into a cellular automata webcam: discrete cells, rule evolution, layer color, beat inject — a full cellular automata video tool in one tab.
TekDetek is not completely free. Swipe CA looks on phone and edit for free. Adding the CA node on the desktop graph, or a clean unlimited export, is Pro. Free record is watermarked and 20 seconds.
Free
Open the app. Swipe and edit looks — phone reaction-diffusion and cellular automata included. Luma detection. Hand. Watermarked MP4 or PNG up to 20 seconds. Watermarked OBS up to 5 minutes (restart anytime).
Pro
Clean export — no watermark. Record and OBS as long as you want. Full preset library, Shuffle, Depth, Alt ASCII. Add RD, CA, PreText, GEO 3D, and Sonify on the desktop graph. Higher detection caps. Buy Pro on Gumroad.
Layers, waves, beat inject
Stack layers with a hue each. Waves move the field. Beat inject drops new geometry instead of wiping the grid — useful as a CA beat visual on four-on-the-floor tests.
Parameters live on the CA node. Phone: swipe the CA family, then EDIT.
Cellular automata vs reaction-diffusion
CA is stepped and grid-native. Reaction-diffusion is a continuous field. Same INPUT, different middle node. See also all nodes.
