WPF Transition Framework, WTF?

Dax Pandhi writes that WTF 0.9 is available for download.

WTF provides easy XAML based access to over 8 most basic and useful transitions including blur, fade, slide, and zoom. WTF is fully compatible with any WPF control - including custom and 3rd party controls. You can use unlimited WTFs in your app - and you get complete controls on the transitions whether they’re timed or triggered. Oh, and WTF is free!!

Check out the sample WPF code.
