Here's the source to the BrowserFlow sample I showed at PDC 2009.  This sample requires the Silverlight 4 Beta which you can find here.   The sample uses the combination of the WebBrowser Control and HTMLBrush to display an interactive Ad that also plays well with the Silverlight animation system.  Click the image below to run the sample (note that it needs to be installed to run).
