Developer Ian Cadle open-sourced ultra-elements, a real-time elemental spell VFX lab for three.js (WebGL2) with 39 tunable spells across ten elements and three hybrids, MIT-licensed. Each spell ships with its own panel of sliders, colors and presets for live tweaking. The author suggests handing the repo to your AI agent to generate the exact spell you need — the codebase doubles as an LLM extension template. Runs locally via npm install.
