Well this surprised me.
The MS Live Labs demo sites - Contoso Bicycle Club
and Contoso University
- are actually Windows Live services in disguise.
Both sites are demos of Windows Live Quick Applications. Essentially mash-ups of various WL services and rich media experiences like Silverlight streaming, storing their content entirely in "the cloud" and available to download and customise as "out-of-the-box" web solutions.
Cool huh!? Check out the River Thames bike cam video on the Contoso Bicycle Club demo site.
