The Close Encounters hat is a nod to the incredible movie -- with lights and sounds that mimic the mother ship, all stowed under the brim. A vibration sensor triggers the action, while the NeoPixels and Piezo buzzer provide the show. Get ready to change up that next kiss or rock a quiet movie theater.

Taking inspiration from the helical Guggenheim museum, this project coils a contiguous reel of NeoPixels around a dapper top hat to create a wearable scrolling message display you can control with your iOS/Android phone or tablet.
