From the README

Blow on your screen to fog it up, then write on it — just like a steamy bathroom mirror, powered by your breath and your hands.

Everyone has drawn a heart on a foggy bathroom mirror. Nobody expects their laptop or phone screen to do it. Fog Mirror listens to your breath through the microphone, fogs up a live mirror of your camera feed, and lets you wipe a message into it with a finger on a touchscreen — or by pinching in thin air if you're on desktop.

Camera-AI demos are usually dry tech showcases — hand skeletons and bounding boxes on a debug overlay.
