All 45 demos

tuiwasm runs Go's terminal-UI libraries — tcell for the screen layer, and the Charm stack above it: lipgloss for styling, bubbletea for the update loop, glamour for Markdown — inside a browser tab, drawing into a real terminal emulator built on xterm-go. Every demo below is the same WebAssembly binary with a different query string; each link opens it running.

Screen demos — they paint cells and read keys

• aquarium fish swimming past swaying seaweed
• atom electrons on tilted orbits round a glowing nucleus
• aurora curtains of light, folding, with the creases where they turn
• boids flocking by separation, alignment and cohesion
• bonsai a bonsai tree growing branch by branch
• bounce the screensaver logo, and the wait for it to hit a corner
• boxes tcell's own boxes demo — random boxes, timed
• clock an analog clock, after aclock
• colors tcell's own colors demo — boxes cycling through the palette
• cube a rotating wireframe solid, shaded by depth
• donut a lit torus with a z-buffer
• fire a heat grid seeded with noise and cooled upward
• fireworks shells that rise, burst and droop into willows
• flow particles carried through a divergence-free curl-noise field
• frost a crystal growing by diffusion-limited aggregation
• julia a Julia set morphing as its parameter walks the cardioid
• langton Langton's ants: chaos, then the highway
• lavalamp wax that heats, rises, cools and sinks
• life Conway's life, colored by how long a cell has lived
• lightning a branching discharge: leader, return stroke, afterglow
• magnetosphere the logo from magnetosphere.net, counter-scrolling
• matrix falling columns of glyphs
• maze a maze carved by backtracking, then solved
• metaballs blobs that bulge and merge as they approach
• moire two drifting ripples interfering
• parrot the party parrot, rolling once around the hue wheel
• pendulum double pendulums released together, shearing apart
• physarum slime mold laying trails and building a transport network
• pipes pipes growing and turning, with correct elbows
• plasma summed sine waves of position, offset by time
• proxima Escape from Proxima 5 — gdamore's tcell space shooter
• proxima2 Escape from Proxima 5 on tcell v2 — the same game, one major back
• rain drops with depth, slant, streaks and splashes
• reaction Gray-Scott reaction-diffusion: spots that divide into a labyrinth
• ripple a ripple tank: rain falling, rings meeting and interfering
• sand grains heaping at their angle of repose
• snow flakes that sway, settle and drift into banks
• starfield stars streaming past the viewer
• tunnel flying down a textured tube
• unicode tcell's own unicode demo — wide, combining and emoji glyphs
• widgets tview — a flexbox of lists, tables and text views on tcell v2
• wolfram elementary cellular automata scrolling upward - 30, 90, 110

Text demos — they write styled text

• charts asciigraph — a line plot in cells
• styles lipgloss — borders, color, alignment
• tables go-pretty — the wasm compatibility matrix
