Richard Griffin has created a 3D Flip Action that can be applied to any UI Element.
After reading Jobi Joy’s post about a 3D Flip Control he had built. It gave me an idea about creating a Silverlight 3D Flip Action that can be applied to any UIElement. It also meant that I got to play with the new Plane Projection bits in SL 3.0. To do this sort of interaction in WPF I use a series of data templates that using template binding for the back and front controls, pretty much a standard mechanism that you see around.
