PatternLab vs Wonder Circuits

Discover the beauty of patterns. PatternLab is a creative sandbox for exploring cellular automata — simple rules that give rise to endless complexity. Inspired by Conway’s Game of Life, PatternLab lets you draw, experiment, and watch living patterns unfold in real time. Whether you’re curious about math, love puzzles, or just want to relax and watch mesmerizing shapes evolve, PatternLab makes science playful and accessible. Features: • Multiple rule sets: Conway, Seeds, Maze, Day & Night • Pre-built patterns: Glider, Blinker, Pulsar, and more • Custom drawing tools to create your own designs • Adjustable grid size and simulation speed • Color themes including high contrast & accessibility modes • Undo/redo support for fast experimentation Why you’ll love it: • Relax and watch infinite patterns evolve • Spark creativity with mathematical art • Learn about complex systems in a hands-on way PatternLab is perfect for students, creators, and anyone who enjoys interactive experiments. Dive in, play with rules, and see how small changes create surprising results.

Build a little computer, one working machine at a time. Wonder Circuits is a hands-on digital logic lab for iPhone and iPad: connect a switch to a lamp, make a clock pulse, add binary numbers, then explore a visible 4-bit computer. 71 guided experiments across 13 chapters turn Boolean gates, timing, carry, memory and control into machines you can build and run. Connect parts, change an input and see what happens. Review what you learned in the concept handbook. The complete Invent Lab is free: build your own logic machines, adjust parts, save reusable modules and share offline blueprints. The first 12 campaign machines are also free. One optional purchase unlocks the remaining 59 machines and all future core content. No subscription or consumables; campaign levels still progress in order. Works offline. No accounts, ads or tracking. This is a digital-signal learning sandbox, not an analog electronics simulator: it does not model voltage or current.
