Whenever you merge a PR, Octocat will do a randomly generated dance as a reward for your hard work.
This is an IoT project built using an ESP8266 and the github API. It parses your github event feed every 3 or so seconds and if a PR is merged, generates some dance patterns for a connected servo. The servo is connected to the octocat skeleton which is made out of left over cardboard packaging found around my flat.
This little octocat is released under the MIT licence and can be found here on Github.
