Vizza Logo

A collection of interactive GPU-accelerated simulations for fun and beauty. Features a friendly UI that puts you in control.

How to play

Windows, MacOS, and Linux are supported.

Download the latest version for your platform from the releases page.

  • For Windows: Vizza_<version>_x64-setup.exe OR Vizza_<version>_x64_en-US.msi, both are equivalent.
  • For MacOS: Vizza_<version>_aarch64.dmg for Apple Silicon, Vizza_<version>_x64.dmg for Intel.
  • For Linux: Vizza-<version>-1.x86_64.rpm or Vizza_<version>_amd64.AppImage or Vizza_<version>_amd64.deb

Then, open the downloaded file and install the app, usually by double-clicking on it. You'll have to click past security warnings because I haven't paid for a developer certificate yet.

Once the app is installed, you can run it like any other app. Presets and color schemes you create will be saved to your Documents folder.

Simulations

Slime Mold

Agent-based simulation where creatures follow trails to create emergent networks.
