About

Flocking Simulator

Explore emergent behavior and steering rules with a "boids" simulation. Adjust forces like separation, alignment, and cohesion to create lifelike motion. Experiment with visual options and observe instant reactions to your changes.

Highlights
  • Adjustable flocking forces (separation, alignment, cohesion)
  • Customizable perception radius, speed, and steering
  • Visual options: boid shape, color modes, debug overlays
  • Real-time swarm reaction to parameter changes
  • Learning emergent behavior and steering rules
  • Generative visuals and relaxing motion

Flocking Simulator is a real-time “boids” playground where simple rules create surprisingly lifelike motion. Build your perfect swarm by adjusting the core forces: • Separation, Alignment, Cohesion • Perception radius, max speed, max steer • Drag (friction), noise (jitter), bias • Optional wall bouncing Visual options: • Triangle or circle boids • Color modes: Solid, Velocity, Rainbow • Debug overlays: vision radius, direction vectors, stats/FPS Great for: • Learning emergent behavior and steering rules • Generative visuals and relaxing motion • Quick experiments—change a slider and watch the swarm react instantly Note: Fast motion and bright colors may affect users sensitive to motion.

Groundfall is an educational nuclear blast simulator built on declassified physics models. Place a detonation on a map and visualize blast zones, thermal radiation, fallout patterns, and estimated human impact. Groundfall is designed to help users understand the real-world consequences of nuclear weapons through clear simulations, historical context, and preparedness information. WHAT YOU CAN DO - Simulate nuclear weapon effects on any city or location - Compare historical and modern weapon yields - View blast, thermal, radiation, and fallout zones - Explore real-world conflict scenarios - Analyze fallout direction using wind data - Review casualty and damage estimates - Learn about nuclear physics, arsenals, history, and preparedness - Save and export simulation results FREE STARTER MODE Groundfall is free to download and includes limited access so you can test the core simulator before upgrading. GROUNDFALL FULL ACCESS Unlock the complete app with a one-time lifetime license. No subscription. Full Access includes unlimited simulations, all weapons, conflict scenarios, advanced fallout tools, export features, live nuclear news, preparedness tools, and future premium features. EDUCATIONAL PURPOSE Groundfall is not a game and does not promote violence. It is an educational tool for understanding the destructive effects of nuclear weapons and the importance of prevention, preparedness, and informed public awareness. PRIVACY Groundfall does not require an account. Simulations are processed on device where possible, and the app is designed to minimize data collection.
