Description: Watch simple rules create extraordinary complexity. Cellular Automata is the ultimate implementation of Conway's Game of Life. Built completely natively from the ground up, it transforms your device into a high-performance engine of infinite digital evolution and ambient audiovisual meditation. If you are a generative art enthusiast, a mathematics student, or just looking for a mesmerizing visualization to help you relax, we built this for you. EVOLVE YOUR WORLD Turn memories and text into living math. Import any photo from your camera roll, type a custom message, or load one of 21 included NASA space images (including Hubble captures). Watch as they transform into a living cellular grid, perfectly preserving the original pixel colors as the simulation evolves. AUDIO-REACTIVE GENERATIVE ART Turn math into a sensory experience. Cellular Automata features 10 built-in ambient and upbeat music tracks. Turn on audio-reactive colors and watch your grids and uploaded photos pulse, shimmer, and shift hues in real-time to the bass, mids, and beats of the music. Deep Customization of up to 6 stunning color presets with a full 0-100% hue shift slider. PHOTO UPLOAD WITH EDGE DETECTION Upload your photos into the Game of Life engine with the easy to use edge, brightness, dither or random selection to set initial patterns for the simulation and watch your photos come to life! SHARE YOUR UNIVERSE Created a mesmerizing loop or a stunning chaotic pattern? Instantly export high-resolution snapshots or generate animated GIFs of your simulation. The app seamlessly captures your last 3 seconds of history, including your audio-reactive colors, so you can share your discoveries directly with friends or on social media with a single tap. POWERED BY METAL GPU Experience uncompromised performance. Our custom-built Metal compute engine allows you to run massive 256x256 grids effortlessly with reactive audio coloring. Watch thousands of cells evolve at up to 30 generations per second without dropping a single frame, or switch to a crisp, 1-pixel-per-cell retro mode. TOTAL CONTROL & CUSTOM STAMPS Paint your universe with adjustable brush sizes from 1x1 up to 10x10. Made a mistake? The engine records your last 1,000 generations, allowing you to instantly scrub backward and forward through time. If you create or find a shape you love, extract it as a Custom Stamp to drop into any future simulation. CURATED PATTERN LIBRARY Instantly load 19 iconic, historically significant patterns. Discover classic Still Lifes, Oscillators, and Spaceships. Spawn the Gosper Glider Gun, test the Simkin Glider Gun, or watch the legendary "Acorn" Methuselah evolve for over 5,200 generations.
