ca-mera+

The successor of probably the nerdiest camera app ever made, ca-mera+ uses a cellular automaton to interpret the colors of your camera stream. The resulting images are pixelated and contain unique patterns created by cellular automata. The output can be black and white, or one of several retro color palettes (CGA 4 and 16 colors, 1-bit RGB, etc.). This app provides "selfie" and "split" modes, records video, and lets you change the appearance of the pictures by controlling the automaton application direction, its rules, the resolution, the input brightness, and the input fidelity (i.e. to which extent the cellular automaton is allowed to run freely).
