VirtualRoom vs Dot

This application simulates the acoustics of a room and reproduces the sound signals for the two ears of a virtual listener inside the room. Listening to these signals using headphones gives the impression of being inside the room at the position of the listener. The positions of the sound sources and the listener can be modified in realtime.

Dot-Physics is an interactive particle sandbox where tiny glowing dots follow simple rules and grow into surprising patterns. Choose a preset world, create your own rules, or draw particles directly onto the screen. Change how colours attract, repel, chase, cluster, and spread, then watch the world come alive. Features: • Real-time particle worlds with colourful motion • Creative Mode for custom attraction and repulsion rules • Draw Mode for painting new particles into the simulation • Touch interaction for attracting, repelling, stirring, and dropping dots • Adjustable dot count, speed, damping, radius, and point size • Relaxing ambient background music • Presets for quick experiments and beautiful patterns Dot-Physics is part visual toy, part creative sandbox, and part simple science experiment. There are no scores, timers, or pressure. Just start a world, interact with it, and see what emerges.
