How far can an AI go when asked to build an advanced, animated web experience in a single prompt? Each piece here was generated from one request, with one follow-up allowed for minor corrections. No frameworks, no libraries, no assets: HTML, CSS and JavaScript in one self-contained file.
A scroll-driven descent from the sunlit surface to 4000 metres. Bioluminescent plankton drift on a flow field and flare at your touch, while jellyfish with simulated tentacles pulse through the dark.
A liquid-metal sculpture raymarched in real time. Drops fuse into a morphing core, a charge-and-release gesture detonates it, and four materials (chrome, soap film, dispersive glass, magma) crossfade on demand.
A winged constellation drifts through an imaginary celestial chart. Draw your own constellation and release it into the sky, with a trail of stardust and optional generated chimes.
Draw a crease in space and flip drifting sparks into their home. Line up the ghosts, catch several lights in one fold, and race the clock as tears open in the field.
A cave that only exists where sound has touched it. Pings of light paint the walls for a few heartbeats, but loud echoes wake the things that hunt by listening. Gather seven pearls and slip out through the gate before your own light dies.
A tool for sculpting invisible currents. Drop sources, sinks, vortices and repellers into a curl-noise flow, watch glowing particles trace every streamline, then export a seamless, tileable generative texture for wallpapers and backgrounds.
Every evening, a mother brings two cups of tea to the station. A two-minute story of waiting, told through passing trains, changing seasons and a single amber window. Hold a memory to bring her daughter back beside the bench.
A whole life drawn as one ink line on paper: a heartbeat, childhood loops, a meeting with a red thread, a home, a child who flies off as a kite, a loss. At the end the camera steps back and the life reads as a single drawing. Hold to hurry time.
A neon space-shooter roguelike. Survive escalating waves, harvest shards to trigger slow-motion Overdrive, and draft one of three upgrade modules after every wave — piercing rails, homing swarms, orbiting drones, a siege laser — into a build that can fell the Dreadnought. One life, best run saved.
A runaway tea trolley races through an overgrown greenhouse. Aim a kettle cannon, dodge seed volleys, and vent a screen-clearing steam blast across nine encounters and three mechanical gardeners. Choose a tea blend and draft stackable fittings to get the porcelain to the sky pavilion in one piece.
A Hush is coming from beyond the sky, swallowing sound, then light. Ring a belfry bell in rhythm, raise idle chimes, catch moth-lanterns and cast a Great Bell in five stages before dusk. Five chapters force a choice each, and every run that fails carries echoes back into permanent recollections.
A tower defense where you defend time, not a place. Corruption spreads along a causal graph of historical moments, and wards anchor to a moment in the Past, Present or Future. Each ward has an echo that edits the waves to come, and Divergence Events grow new branches into the timeline mid-run.
Trapped in your father's lighthouse by a rising tide, restore its machinery and signal the rescue launch. Search three rooms, follow a keeper's clues, repair the supply and focus the lens before leaving the light behind.
A stickman runs along a road that keeps running out on him, faster and faster. You are the pen: draw lines to bridge chasms, ramp cliffs and roof him from a sky that drips ink, while erasers roll in to eat the road itself. Ink flows back with time — speed does not, and stall five seconds at a wall and the page throws him back a heart poorer.
A Balatro-style roguelike played with dice. Roll five 3D dice, reroll the ones you don't want and score poker-style hands as Chips × Mult against escalating blinds and bosses. Jokers bend the rules, Stars level up hands, and Glyphs rewrite the faces of your dice for good.
A ten-second motion piece on its own premise. A typed prompt collapses into a spark that bursts into slammed words, particles, a flipping tile grid and a carousel of windows, then settles on one line. The last full stop becomes the caret of the next loop.
An eighteen-second loop asking “AI will replace you. Will it kill you?” Human silhouettes pass through a scanner, oversized type fills the screen, and a pulse goes flat before beating again. The question stays open.
The JavaScript event loop, explained by scrolling. Six chapters run real snippets step by step as calls fly between the call stack, Web APIs, the task and microtask queues and the render step. A live lab lets you freeze the main thread yourself.
A poem written by a murmuration of starlings over a lake at dusk. Thousands of birds gather into each line and scatter again while the sun sets, then come down into the reeds for the night and rise at dawn. Be the wind or the hawk, call them to you, or give them your own words to write.
Five miniature places hang from a wooden mobile: a village, an orchard, a lighthouse, a borrowed sea and a solitary house. Drag to turn the sculpture, send a breeze through its strings, or change the light from morning to night. Visit each island, listen to synthesized chimes and save a postcard.
