Looking for an easy to use and highly configurable information radiator? Then Wallboardr might be for you.
Wallboardr lets you define a set of boards which contain screens of information that are displayed in a rotating cycle. Out of the box you can define textual messages, but through a series of plugins, you can hook into external systems to display whatever you want.

Notice
At this point, Wallboardr is still in development and is still building up functionality to be properly released. In the meantime the code is available on Bitbucket if you are interested in cloning and running your own copy. Update to the stable bookmark if you want something that is somewhat stable. The system should be quite usable, but certain things may still be a bit manual and undocumented, so I'm not prepared to say people should use it.
If you have any feedback/requests, you can go to use the issue tracker.
Work is tracked on Trello. You can see what ideas and plans are in the making.
