I'm downloading this later on tonight and I really hope it works as you say it does. Animating things is such a chore when I just need a simple glow on an image or a little 'jitter' when a user clicks on an image.

All the best and here's to you! :D

Great job!

But in WPF StoryBoard.Completed event is not triggered always (i think it's a bug in WPF), therefore group animation not working as expected.
