We mounted waterproof RGB LED strings on fishing poles secured in small hydration backpacks and controlled them using an AdaFruit Feather HUZZAH (ESP8266). The ESP8266 board also runs a mesh network, allowing the Pole Packs to synchronize their sequences. 20 backpacks and a tower system were built for Burning Man 2017. Further development of coordination is anticipated for later events.

And later was 2018 where we upgraded to and ESP32 board, added a single (usually red) pixel in a box that looked like HAL9000, and  a speaker with some audio playback.

Someday I'll put more details in here... after getting permission from the client.
