The various Salesforce Lightning component prototypes published here are now available in the Metillium Lightning Prototypes Github repository. You can still deploy them through the unmanaged package but having the repo makes it easier to view the code in one place, allows others to contribute to it, and allows issues to be created against it.
One can use the Deploy to Salesforce image from the repo’s home page to deploy to their org using Andy Fawcett’s Heroku app.
Pull requests are welcomed and encouraged!
