I'm not sure how many of you have heard of the new Microsoft Surface product (if you haven't, are you living under a rock?!?! ;-) ), but in one of the demo videos, they show how you can take images and resize/rotate them by using your fingertips.  Well, the same thing can be done using Silverlight through a web application.  Delay has posted a great sample Silverlight application that does the same thing!  It's pretty awesome app that shows the power of Silverlight!  If you have the time, check out the live demo or get its source code (you'll need Orcas Beta 1 to run the project).
