This week I've been integrating a Trackball component (found in the WinFX examples on Robert Hogue's site) and playing with 3D animations in WPF apps. So, you're probably wondering what it looks like when you have a multi-colored matrix of bouncing, spinning cubes. Well you're in luck:

In the words of Raymond: "Necessary? No. Cool? Absolutely." But seriously... I'm glad I was able to find some time to get to this little exercise. While my final product doesn't really provide much value, the knowledge gained in the process can be re-used.

Also, Hogue's trackball is pretty sweet. I like it better than the one currently out on GotDotNet. It's very easy to hook up and I don't see why you wouldn't use it all the time while experimenting with 3D.
