So I created one such behavior. I used this behavior in my TwitterBug sample at TechEd recently,and thought it Could use a dedicated blog post. :-)
Here is a screenshot,which really doesn’t do much justice to something interactive. So go ahead,and click it to run the sample live. Click around on the images. And if you’re wondering how its done,go ahead and download the code. You’ll see a BouncingPlane class that derives from Behavior......
