Thirty-two small, self-contained browser tools. No frameworks, no dependencies, no tracking: just open and use.
A virtual keyboard of ~3,700 math symbols with search, recent-history, copy and download.
LaunchText-based Boolean expression evaluator with color-coded evaluation, expression trees, truth tables and simplification.
LaunchArbitrary-precision math in your browser: big-number calculator, calculus and more, up to 100,000 digits.
LaunchDigits of π streaming across the screen from a Gibbons spigot: 6 BigInts, unbounded, no floating point.
LaunchMulti-threaded mathematical constant digit calculator using Web Workers with BigInt arithmetic. 38 constants, streaming output.
LaunchInfinite scrolling display of the ABACABA fractal sequence, colored by letter.
LaunchOpen envelopes one by one and decide when to stop. A secretary problem game.
LaunchPoker-style betting with Uno cards. Most hand-to-community matches wins the pot.
LaunchRoll the die, climb ladders, dodge snakes. First to 100 wins. 2-4 players with AI.
LaunchFind the one item that's different: visual patterns, numbers, words, or emoji. Configurable grid, timer, decoys, and difficulty.
LaunchA fast, minimal code editor with syntax styling, light/dark theme and keyboard-friendly controls.
LaunchA toolchain for TM0, a tiny Turing-machine dialect: write assembly or high-level IR, compile to .tm0 and watch it run.
LaunchAn end-to-end encrypted messaging demo with a Signal-style Double Ratchet key exchange, running entirely in your browser.
LaunchEncrypted peer-to-peer messaging with WebRTC: room names, optional passwords, group mesh, file transfer. No server, no tracking.
LaunchL-system fractal explorer with axiom/rule editor, turtle graphics, and 13 presets: Koch, Sierpinski, dragon curve, Hilbert, and more.
LaunchSpace-filling Hilbert curve on a 2n × 2n grid, colored by a smooth rainbow gradient. Animate, step through, or explore orders 1–8.
LaunchInteractive gemstone renderer: 23 cuts, realistic IOR/dispersion, 10 stone presets, and CPU path tracing.
LaunchGPU gallery with no assets: signed-distance-field scenes rendered via ray marching in a WebGL 2 fragment shader. 6 scenes, 4 materials.
LaunchRed and Blue cells fight for territory in a probabilistic cellular automaton with 12 themes.
LaunchAll 256 elementary cellular automaton rules, from Rule 30 chaos to Rule 110 Turing-completeness.
LaunchTotalistic cellular automaton with 2–64 states: each cell = (left + center + right) mod N. Hue-colored, Sierpinski to chaos.
LaunchConfigurable stress tests: prime sieve, matrix multiply, SHA-256 hashing, regex backtracking, with live performance monitoring and thermal throttle detection.
LaunchMulti-threaded mathematical constant digit calculator: 38 constants, Web Workers, BigInt arithmetic, streaming output.
LaunchAn interactive Navier-Stokes flow field with views for direction, speed, curl, pressure, and heat. Drag to stir, pour heat from the nozzle.
LaunchAn infinite procedural world: perfect mazes, Hilbert curves, caves, biomes and more, computed in a Web Worker. Pan, zoom, play, dodge hunters, slide on ice.
LaunchDual-mode crystal growth: DLA random walkers with point/line/square seeds, stickiness, and phase-field Reiter model with hex symmetry. SVG export.
LaunchAll tools bundled into one self-contained HTML file. Open offline, no server needed.

ViewA domain-specific language for electronic design automation: schematic capture and PCB layout, with ~700 built-in functions and a full spec.
DetailsA collection of experiments in cellular automata, generative grammar, math tooling, computing machines and playful interfaces. Everything runs entirely in your browser: nothing is uploaded, nothing is tracked.
