I'm constantly impressed by the ESP32 and have dabbled in a few project ideas. You could even use them to talk to other ESP32 devices (in other dresses!) using WiFi/UDP, Bluetooth LE or Espressif's own 'ESP-Now' mesh networking (which recently blew my mind). I've done a few RGB LED Matrix based ESP32 projects now. This project has given me a few ideas. Thanks!
