Addressable leds are a lot cooler when you can control them from your wrist! Controlling things with a combination of the touch ring and accelerometer is a pretty nice interface. I can imagine setting the color of a whole room in my house by holding the touch ring and twisting my wrist until I got the color I wanted. This was pretty simple to code but you can find the watch side of things on my GitHub repository in the _Round_DemoAndTesting program.
