The Zen Scale
A marble drops onto a wooden scale above a koi pond. Tilt your head to tip the scale and roll it into the glowing well — raise a hand to sprout a peg and save it from the edge. Slow, calm, and very hard to put down.

Motion Arcade is a neon playground that runs on nothing but your webcam. Wave, swipe, pinch, rally — every move is read in real time, so the game reacts the instant you do. No controller. No install. Just you.
We ask once. The webcam feed never leaves your browser — all tracking runs on-device.
MediaPipe locks onto 21 hand landmarks in real time. Wave, pinch, swipe, or rally.
Your fingertip is the cursor. Your open palm is the paddle. Cabinets respond instantly.
Every cabinet is built around a single gesture — a fingertip, an open palm, a swipe. Step in front of the camera and the game shapes itself around you.
Every cabinet runs on in-browser machine learning that locates your hands and face dozens of times per second. The games read those landmark positions, not the video itself, and the camera feed is processed entirely on your device. Nothing you do in front of the lens is uploaded, recorded, or seen by anyone.
Curious how a browser tab pulls that off, or how to set up a room that tracks well? The guides cover the tracking tech, camera setup, and accessibility across every cabinet, and the about page explains the project itself.
No login, no download. Allow the camera, raise a hand, and the arcade lights up around you.
