Dr. Lucy Rogers took her broken wrist cast and turned it into a cheerful thing. She dazzled her cast with some electronics from Adafruit, including the Flora, Bluefruit, and Neopixels. Bluefruit is a Bluetooth module that connects to her phone. The phone is listening to the latest CheerLights color and sends it her cast using Bluetooth.
The CheerLights Cast made its debut at the ThingMonk conference and lots of people sent Tweets controlling the color of Dr. Lucy’s cast.
