Zack made Myo 2 Blink, an interesting Octoblu example using a Myo gesture armband to change the color of a blink(1) notification light depending on hand gestures. (If you've not heard of Octoblu before, check it out. If you have heterogeneous IoT or other devices talking to each other, you may need it. It's a visual tool for describing how data should flow, connect, or be transformed and analyzed) To make it work, Zack created a small iOS app that talks to the Myo band via Bluetooth and publishes blink(1) color changes to the Octoblu Web API over the cellular network. It's pretty slick for a simple demo.
