SimTigerBeetle: TigerBeetle in WebAssembly
SimTigerBeetle runs TigerBeetle — the high-performance financial accounting database — compiled to WebAssembly in the browser. An interactive simulator for understanding TigerBeetle's consistency model and transaction semantics without local setup.
Genetic Boids: Evolutionary Flocking Simulation
Genetic Boids combines Craig Reynolds' flocking algorithm with evolutionary mechanics — up to 800 entities exhibit alignment, separation, and cohesion, with lifespan and signal parameters that drive emergent population behavior.
Stochastic Processes and Simulations: An ML Perspective
Stochastic Processes and Simulations: A Machine Learning Perspective by Vincent Granville — covers point processes, Poisson-binomial processes, GPU clustering, and extreme value theory with Python code. Bridges probability theory and ML's simulation-heavy approach to uncertainty.
Gauntlet: DeFi Economic Security Platform
Gauntlet is a DeFi economic security platform that uses agent-based simulation to stress-test protocol parameters — finding safe collateral ratios, liquidation thresholds, and interest rate curves for lending protocols. The risk management layer that keeps Aave and Compound from getting drained.
Do Androids Grow Electric Plants?
Alex's technical notes on SPACEFILLER's digital plant simulations — particle systems with repulsive forces, spring connections, friction, and Boids-inspired velocity matching that produce organic-looking lo-fi animated plants. A good introduction to particle simulation forces for creative coding.
Ian Cheng Interview: A Portal to Infinity
Ian Cheng in conversation about his lifeform simulations and art practice — infinite open-ended worlds that evolve without predetermined outcomes. Cheng is one of the few artists working seriously with simulation and emergence as a medium.
Traffic Waves Simulation
Lewis Lehe's interactive browser simulation of traffic waves — slow one car down and watch a ripple of phantom congestion propagate backward through traffic. Makes emergent complex-systems behavior viscerally tangible.
Flocks, Herds, and Schools: A Distributed Behavioral Model
Craig Reynolds's 1987 SIGGRAPH paper on Boids — the three-rule algorithm (separation, alignment, cohesion) that produces realistic flocking behavior from local agent interactions alone. One of the most cited demonstrations that complex group behavior emerges from simple rules, not central coordination.
In a First, an Entire Organism Is Simulated by Software
The 2012 announcement that Stanford researchers had built the first complete computational model of a living organism — Mycoplasma genitalium — simulating every known molecular interaction in the cell. A landmark in computational biology.
CameraSim: SLR Photography Demystified
CameraSim is a browser-based DSLR camera simulator that lets you adjust aperture, shutter speed, ISO, and focal length and see the effect on a simulated photo in real time. A practical tool for learning exposure without burning through film or battery.
