A quadruped you can drive live in a browser tab — physics, the walking policy, and the rendering all run client-side; the server only hands over files. Added September 2026.

Fly a kite in real-feeling wind: gusts that travel downwind, wakes off the trees, a line that sags, stretches and snaps. A dozen classic kites and your own designs, traction foils and a kite-surfing kite, a control-line plane, drones, and a fighter-kite duel on glass-coated line. All the physics runs in your browser. Added October 2026.

A space empire game measured on the Kardashev scale.

A band of dogs living on rolling country — playing, patrolling, hunting deer, squabbling, raising pups — simulated live in your browser, where each dog decides for itself and nothing is decided in advance. Drag to look around, click a dog to follow it, or step in as the person and feed, groom and pat them. Turn the sound on to hear each howl and growl from where it was made. Added September 2026.

A webcam dance coach. Stan calls out moves and reacts to how well you match them (MediaPipe pose/gesture tracking, right in the browser — nothing uploaded), with a live musician (Oscar, or a pickable alternate) scoring the session. Full name Austin “Dance” ParTay; everyone just calls him Stan. Added September 2026.

Call someone else who has the page open. They get a popup they can join or reject; joining puts you both in a room with video, audio, and a chat box. Added September 2026.

A room of small creatures that only make sounds — no words, no shared symbols, nothing to read. They play peekaboo with you and take turns hiding; they get tired, take breaks, want the spotlight, and take drum solos that end when they run out of breath rather than when a timer says so. Added August 2026.

The Korean flower-card game. 2–4 seats, any mix of human and computer opponents (with Korean-named difficulty tiers), the full ruleset — bombs, shakes, misdeals, nagari — and stakes that scale with the deck you pick. Added August 2026.

Classic falling-block puzzle with a kickable ball mixed in, four escalating phases, and a shot at Total Victory. Added August 2026.

Learn and practice Morse code — a long-running personal project, not a new addition to this repo. Lives at its own address, pehr.net/morseall.
