The InfoScreen is a single-page website, which serves up some interesting and important information in the RaumZeitLabor hackerspace in Mannheim, Germany.
It uses RaumZeitLabor's Cosm feed for important data such as electricity usage or temperature, and shows related tweets as well as the timetable of the closest tram station.
You can find a running installation at http://cosm.tiefpunkt.com/infoscreen/
If you want to setup the InfoScreen, you should follow these instructions: https://wiki.raumzeitlabor.de/wiki/InfoScreen (Sorry, atm only in german!)
