Using LEDs to visualize location data.

Breadcrumbs is a 3d printed map of my town lined with LEDs that light up based on location data. A companion app pairs with an ESP32 to sync my current location to a specific LED on the map. As I go about my day, a trail of lit LEDs exposes where I’ve been that day. To anyone who is able to see the 3d printed map and have genral knowledge of my town, they are able to infer information about me purly based on lights.
