Fish Eye Control in Silverlight
Martin Grayson has a fantastic post, along with code, on one of the best Fish Eye controls I’ve seen implemented.
Using this as a basis we have been working on migration to Silverlight, and finally got the time to get this working.
The code is still a bit rough so I can’t publish it, but it does demonstrate that it can be done. The main changes we needed to make were due to the lack of a Mouse position meaning we needed to pass this into the methods from our MouseOver event. We also needed to create StoryBoards on the fly for the animation, I have some concerns here about memory usage as we’re currently not cleaning everything up - more work needed 
Screen shot below, actual examples to follow soon.
