Core Simulations
7Doppler Effect
Interactive simulation of the Doppler Effect — visualizes how the frequency of sound waves shifts with relative motion between source and observer.
Optics Lab
Web-based geometric optics simulation. Supports ray sources, parallel and divergent beams, mirrors, lenses, beam splitters, and refraction interfaces.
Oscillations And Chaos
Collection of four classical mechanics simulations exploring oscillations and chaos: single spring, double spring, pendulum, and double pendulum.
Qubit Sketch
Drag-and-drop quantum circuit builder with a live state simulator. Place quantum gates and watch probabilities, amplitudes, Bloch spheres, and measurements update in real time.
Resonance
Interactive simulation of resonance in driven oscillating systems. Visualizes driven mass-spring systems and Chladni plate patterns.
Track Lab
Browser-based video motion-analysis tool. Load a video, calibrate real-world distances, and auto-track objects across frames using computer vision.
Wave Composer
Three-screen VoceVista-style real-time voice-analysis simulation. Analyzes microphone input for waveform, spectrum, and composition.
Classic & PhET Ports
6Electric Field Of Dreams
SceneryStack port of the PhET 'Electric Field of Dreams' simulation. Place charged particles and observe Coulomb interactions and an adjustable uniform external field.
Lady Bug
SceneryStack port of the PhET 'Ladybug Motion 2D' simulation. Explore 2D motion, position, velocity, and acceleration using a ladybug on a rotating platform.
Lunar Lander
SceneryStack port of the classic PhET Flash 'Lunar Lander' simulation. Pilot a lunar module to a soft landing by managing thrust and tilt against gravity.
Maze Game
SceneryStack port of the PhET 'Maze Game' simulation. Drive a particle through tile-based mazes using position, velocity, or acceleration control modes.
Moving Man
SceneryStack port of the PhET Java 'Moving Man' simulation. Explore 1D kinematics by dragging a man or using position/velocity/acceleration sliders.
Radio Waves
SceneryStack port of the PhET 'Radio Waves & Electromagnetic Fields' simulation, rebuilt from the legacy PIXI.js + Backbone version. Wiggle an electron and watch EM radiation propagate.
