THE PLAYGROUND

Go on. Try something.

Small working instruments, built to answer a question. No sign-in. Camera and chosen media stay on your device.

The direct hand-control experiment with camera preview

COMPUTER VISION / PROTOTYPE

Your hands move it.

Hands apart: expand. Together: shrink. Tilt the line between your palms: rotate. Camera starts only when you click and stops when you leave.

Try hand control

Downloads an on-device model. Requires a camera and permission. Occlusion, lighting and browser support affect tracking.

COMPUTER VISION / RESEARCH TRIAL

See the movement.

Run the licensed sample or choose a short video. Inspect the detected people, sampled paths and broken track segments, then export the observations.

Run the trial

Downloads a person detector. Five samples per second, image coordinates. Not tactical analysis, technique coaching or court-distance measurement.

ORIGINAL EXPERIMENT / SIMULATION

Money behaves like a gas.

Two thousand equal agents exchange money at random. Nobody is smarter, nobody cheats, and the total stays the same. What does the distribution become?

Run the exchange model

A mathematical model, not an explanation of all real-world inequality.
