For Hackaday Supercon, I'm creating a SAO (simple add on) that hosts an ESP32-s3 microcontroller with a built-in Wi-Fi radio, which visualizes the invisible Wi-Fi environment around you.

Using a CircuitPython example, I've created a mockup of a circuit board that sorts packets into different colors, and displays them on a clock according to which of the 12 Wi-Fi channels the packet appeared on.
