VIZZY

A toy VJ instrument that's fun to play with: type a prompt, a local LLM dreams up the visual, a native GPU engine renders it, and you ride the faders while everything wobbles to the music.

SETUP // GIVE VIZZY A BRAIN
  1. The lazy way: just open Vizzy. If it can't find an LLM it offers to download Ollama and a model for you, with a picker showing what each model needs (RAM, disk). Done. The steps below are only for doing it by hand.
  2. Install Ollama — the local LLM runtime Vizzy talks to. Nothing leaves your machine; no API keys, no cloud. 
    # macOS    download from ollama.com/download, or: brew install --cask ollama-app
# Windows  download + run the installer from ollama.com/download
# Linux    curl -fsSL https://ollama.com/install.sh | sh
  3. Make sure it's running. The macOS/Windows desktop app starts the server for you (look for the llama in your menu bar / tray). On Linux, or if you installed CLI-only: 
    ollama serve
    Vizzy expects it on the default port, 11434.
  4. Pull a model — the default Vizzy asks for is qwen2.5-coder (~4.7 GB): 
    ollama pull qwen2.5-coder
    The model fills in a small JSON patch (not raw shader code), so even small models reliably produce working visuals — change the model name in Vizzy's top bar. Bigger model = better taste, slower drops.
  5. Open Vizzy, type a prompt into a deck, hit Generate. First generation warms the model up, then it flows.

Builds are fresh off CI and unsigned, because Apple wants £99 a year to notarize apps and this is a free toy — we ain't paying to notarize nuffink. So macOS will claim Vizzy "is damaged and can't be opened". It isn't damaged; Apple is just sulking about the £99. Drag Vizzy.app to Applications, then run xattr -dr com.apple.quarantine /Applications/Vizzy.app once and it opens forever after. This very background is a little plasma shader — Vizzy's native engine makes this kind of thing all night, only faster and with more knobs.
