If you are into photography you should definitely take a look at Photosynth. Photosynth allows you to reconstruct a scene or object from a bunch of flat photographs. It allows for an interesting new new photoviewing experience.
Photosynth also uses the Deepzoom (originally called Seadragon) capabilities which you can use in your own Silverlight apps.
For more information about similar projects take a look at the Microsoft LiveLabs.
