I have made RGB Goggles using WS2812B LEDs and Arduino Nano. The Arduino based Goggles have many different color animations that can be controlled using a mobile app. The app can communicate with Arduino through Bluetooth Module. Previously we interface WS2812B LED with Arduino and built POV Display using WS2812B LEDs,
