Err... well it sure don't do much yet but if you just can't get enough of spinning a photo around then here is the ClickOnce install.

So far I've tackled some very simple DependencyPropertys, binding, control templating and event triggers. As I always find when learning something like this from scratch - simple things can take a long time. The only reference that I've used so far aside from the MSDN help is an excellent intro to writing WPF custom controls by Mark Miller in a recent episode of dnrTV.
