I had the opportunity to attend MIX '08 this year and I got to see Deep Zoom in action in Silverlight 2.0. Some of you may know Deep Zoom by its old name, Seadragon, however, it is a new beast.
Scott Hanselman goes into detail on how to create a Deep Zoom project in Silverlight and a real life demo.
So what is the big deal? I suggest playing with the
Hard Rock Cafe's memorabilia site which implements it and check out the Bo Diddley guitar in the center. The picture I'm showing off here is in the collection and is the autographs of the Beatles from a letter to a Miami police officer.
The team at Vertigo which created the Hard Rock project have another demo of Deep Zoom.
