SwiftUI Metal shader
Mycelium
A quarter of a million agents, each smelling the trail ahead-left, ahead and ahead-right, turning toward the strongest and laying down more of it. Nothing draws the network — it is what the agents agree on. Drag to bend it. Exports a self-contained MetalKit renderer.
SwiftUI
How it works
Mycelium is a real [[stitchable]] Metal shader, not a video or an image. It runs as a SwiftUI .colorEffect, so it paints any view you attach it to. You shape it with sliders in a live preview, then export the .metal file and the SwiftUI code that uses it. No MSL to write.
