Vizza is a calm, interactive visual sandbox of GPU-accelerated simulations. Shape particles, patterns, flow fields, slime molds, cellular automata, and color gradients into strange, beautiful, emergent motion.
Vizza is an interactive simulation playground built for curiosity, experimentation, and visual beauty.
Explore a growing collection of GPU-accelerated systems that move, react, spread, collide, dissolve, and organize themselves in unexpected ways. Every mode gives you a hands-on way to play with motion, color, and emergent behavior, whether you are making flowing particle fields, organic reaction-diffusion textures, pulsing slime trails, or hypnotic moiré patterns.
This is not about winning or losing. Vizza is about adjusting a system, watching it respond, and finding beauty in the result.
Explore Interactive Simulations
Switch between a variety of visual systems, each with its own behavior and personality:
Slime Mold
Guide an agent-based simulation where tiny creatures follow trails and form branching, organic networks.
Gray-Scott
Experiment with reaction-diffusion patterns that resemble coral, cells, spots, waves, and other natural textures.
Particle Life
Create multi-species particle worlds where attraction and repulsion rules lead to swarms, clusters, or chaotic motion.
Flow
Watch particles drift through shifting flow fields, forming streams, currents, and delicate motion trails.
Pellets
Play with gravity and density-based particle interactions for satisfying, physical-looking movement.
Voronoi
Observe moving Voronoi cells as they shift, compete, and transform into geometric patterns.
Moiré
Generate layered interference patterns with distortion effects for abstract, hypnotic visuals.
Shape the Look
Vizza includes a Gradient Editor for creating custom color schemes that can be used across the simulations. Tune the atmosphere of each system, from soft and meditative to sharp, alien, chaotic, or vibrant.
A Visual Toy for Experimenters
Vizza is made for players who enjoy:
Open a simulation, adjust the controls, and see what happens. Small changes can lead to surprising results.
