See the worlds
actually run.
A wall of real, interactive replays distilled from simulation event logs — a tube day, a Pac-Man game, a Prisoner's Dilemma tournament. Press play on any panel to open it; step through them all without leaving the page.
Game of Life
Conway's automaton as a perfectly observable, deterministic grid world.
London Underground
A live tube graph — eleven lines, hundreds of trains, platforms held as a mutex.
Pac-Man
A self-playing arcade game — ghosts chase a flood-filled distance field.
Tiger POMDP
The canonical POMDP — a hidden tiger, noisy growls, a finite-memory policy.
Recycling Robot
Sutton & Barto's recycling robot — search, wait or recharge under a battery MDP.
Thermostat
A continuous-state HVAC MDP — real-valued temperature, threshold control, noisy dynamics.
Prisoner's Dilemma
Iterated Prisoner's Dilemma with truly simultaneous, synchronous moves.
GTM Sales Funnel
Opportunities through a B2B SaaS funnel, with capacity-capped reps and solutions engineers.
Service Desk
SaaS support tickets through triage and a capacity-capped agent pool to resolution.
Turing's First Example
Turing's 1936 first machine — prints 0 1 0 1 … rightward forever, never halting.
Turing's Second Example
Turing's 1936 second machine — prints growing blocks of 1s by copying the last block and adding one.
Palindrome Decider
A decider that erases matching ends and sweeps inward — halting in Accept or Reject.
Wolfram (2,3) Machine
Wolfram's 2-state, 3-symbol machine — proved universal in 2007 — running on an infinite alternating tape.
Rogozhin (4,6) Machine
Rogozhin's 4-state, 6-symbol universal Turing machine (1996), running on a self-growing tape.
Minsky (7,4) Machine
Marvin Minsky's 7-state, 4-symbol universal Turing machine (1967), halting on a demo input.
