As I am a programmer,and not an artist or animator and I am failing at showing off the best features of WPF in my application. Although I have samples for simple animations for buttons like growing, or having the color fade into something brighter on click but what I am looking for is some showcase button animations and some showcase panel change animations to show off the best features of WPF. Normally I would go for the more subtle changes, but in a couple of cases I need something to really show off the advantages of using WPF over WinForms technology.
Can anyone point me at some button samples and/or panel changing (switching from one panel to the next in a navigation) that really shows of WPF and has that wow factor.
EDIT
Please don't point to http://codeproject.com or the microsoft samples, as I have already perused those at great detail. In fact here are the list of WPF sites in my rss reader (Suggestions for other blogs welcome):
Lester's WPF blog, Ask Dr. WPF, Expression Blend and Design, WPF Wonderland, nerdplusart, Karl On WPF, Windows Presentation Foundation SDK, Josh Smith on WPF, Rob Relyea - Xamlified, The Moth.
I want specific examples, thanks...
