Built a native macOS app for writing and previewing fragment shaders in real time — basically Shadertoy, but as a local Mac app running on Metal.

What it does:

• Write Shadertoy-compatible GLSL and see the output update live as you type

• Multi-buffer support (Buffer A/B/C/D) for effects like Game of Life, feedback trails, etc.

• Texture inputs on any channel

• VS Code-style editor with syntax highlighting

• File history with side-by-side diffs
