I didn't really understand what this was until I scrolled down to the screenshot and realised its a buildwall. May be worth using that term in the summary on GitHub for clarity?
As for the project itself, nice work! I'm a huge fan of buildwalls and think all colocated teams should have one on display somewhere prominent where the whole team can see it most of the time. We literally just started a new team up a couple of weeks ago, are colocated and are using Travis for CI. So your project is about to go up on the wall here right now. Thanks! :)
