Four demos, four ideas, one hand on each
Each of these runs its own mathematics live in your browser — a logit fixed point, a nine-state Glauber chain with its stationary distribution, Schnakenberg entropy production, a maximum-likelihood fit. Nothing is pre-rendered, and every published number on the pages names the file it was read from.

You vs the Model
Play rock–paper–scissors. Your rationality parameter is fitted by maximum likelihood from the choices you make, placed on a scale against measured systems, and then played back at you as a prediction of your next move.
The estimator is the one the project runs on market data.

The Whirlpool
The nine joint states of a two-player game, with probability flowing along the edges between them. Drag the game from a landscape to rock–paper–scissors and the flow stops cancelling.
At the potential end entropy production is exactly zero — a theorem, not a rounding convention.

Ten Little Treasures
A payoff change that leaves the Nash prediction untouched and moves real behaviour from 48% to 96%. Guess where the subjects went, then watch one dial do what Nash cannot.
Every experimental number is from Goeree & Holt, AER 2001.

The Plane
Response asymmetry against dissipation, with Sioux Falls, Dominick's, CAISO, rock–paper–scissors and Blotto as permanent landmarks. Drag your game and watch it leave the line a one-dimensional theory would predict.
Quadrant III is marked empty, because that is the programme's open decisive test.
