Built a custom EEG neural tracker from scratch in Rive using Lua scripting.
Originally tried Unicorn Studio’s blob tracker, but the rendering and control weren’t there, so I rebuilt it fully procedural.
~34 KB without the image.
No textures. No external deps. Just math and draw calls.
Visually artistic, but structurally mapped to real 10–10 EEG electrode positions, so it can plug into actual EEG data if needed.
