SANDBOX LIVE
REPLAYS · 7 INTERACTIVE PLAYERS

The replays,
everywhere they fit.

Several scenarios ship a real, self-contained replay of a simulation run — Pac-Man chomping pellets, a tube day line by line, a Prisoner's Dilemma tournament. Below is the gallery, plus every pattern for getting these onto the site. Each tile loads on demand, so nothing heavy downloads until you ask.
