Any video, redrawn by chess pieces that only make legal moves.

Drop in a clip, up to four minutes, and every frame becomes a tan chessboard. Between frames each piece makes one real chess move into an empty square: queens slide, knights jump, nothing is captured. Built for the Bad Apple!! meme: it opens with a short original shadow animation, or drop in your copy of the shadow-art video and watch it played out in queens. It all runs in your browser; the video is never uploaded.

Three arcade games you play by waving at your webcam.

Your hand is the controller. Steer a paddle to break a wall of bricks, rally against the CPU or a friend, or slide a fighter under a swarm and pinch to fire. The hand tracking runs in your browser, so the camera picture never leaves your device.

An incremental game about one very satisfying key.

Press it to earn juice and tune it until it thocks just right. Then the spacebars arrive, and their rattle is pushing the multiverse apart. Eight Ages, from your desk outward. Progress saves in your browser.

A tower defense game drawn in the margins of a notebook.

Dex, the kid who sits behind you, keeps drawing invaders across your page. Doodle defenders, pick upgrade paths, and scribble out everything he tries. Every five rounds he passes you a note with a new idea. Progress saves in your browser.

Music composed and synthesized in your browser, sample by sample.

Every kick, bassline and reverb tail comes from arithmetic, not recordings. Play Songs to do some work to (when the work needs doing), five albums, one per genre, each telling a story about working in software. Or pick one of 10 genres and a few options, and it writes a brand-new track you can share or download.

A seek-and-find and coloring game for phones and tablets.

Shiny balls are hiding in every picture. In Lost & Found, each one holds something a friend has lost: help 135 friends along the road to the Moon, earn stars and fill a sticker book. In Glitter Color, each holds a secret glitter to color the page with. Progress saves in your browser.

Canvas 2DWeb AudioMade for touch

An arcade shooter that slowly turns into a swarm.

Squads fly in, line up above you and dive. Minute by minute they come from wider angles and break ranks, until they pour in from every side. Your guns fire on their own while you steer, grab crystals and build from twelve weapons, each with an evolution and mods. Shoot down a Warden mid-dive while it tows a captured fighter, and the fighter becomes your wingman. Two bosses join the swarm, at 10:00 and 20:00: last until 30:00 to clear the sector. Between runs, tokens buy Hangar upgrades and new ships, quests unlock more of the arsenal, and five threat levels raise the stakes. Progress saves in your browser.

A tiny platformer that grows with you, one level at a time.

At first, all you can do is walk to a doorway. Every level adds one new possibility: jump, double jump, dash, glide, climb walls, light checkpoints, and slip through crystal gates. Eight little adventures in an overgrown moonlit garden, then remix trails to put it all together. Optional fireflies, instant retries, and progress that saves in your browser.

A soundboard for running D&D's Heroes of the Borderlands starter set.

Walk the party from the Keep's tavern out along the Trail, into the Fens and down into the Caves of Chaos, and the board plays each place. 21 original themes are composed and played live, each with Explore, Tension, Battle and Boss moods that fade in and out as the fight changes. Each place has its own ambience and pads, plus a kit of 147 effects, stingers for victory and natural 20s, and rain or storms on top. Everything crossfades, in one key, as you go.
