I spend some time with WPF this week and came up with a Quicksort demo for Chrome that uses WPF. The video can be found at:

And the sample itself can be downloaded too (It’s at the end of the video). To run it yourself you need Chrome 1.5, the WPF runtime (.NET 3.0) and optionally the Orcas plugin for VS2005 (to open the XAML in VS2005).
