In the Channel9 video showing the 2D on 3D feature found in the 3DTools Codeplex project, we demoed a photo browsing application that made use of 2D on 3D and that talked to Flickr for images. I'm happy to announce that the source code for this application is now available for download. You can get it from here: http://www.codeplex.com/3DTools/Release/ProjectReleases.aspx?ReleaseId=2058
And in case you forgot what it looked like, here's an image of it running.
A Flickr API key isn't included with the source, so in order to actually search for photos yourself you'll need to get a Flickr API key from http://www.flickr.com/services/api/keys/apply/ and then add it to Flickr.cs
