Animation Crash Course (XDEV13205)

I've read plenty of tutorials on interface animation. Ninety percent of them animate a simple pushbutton from one side of the window to the other. Unless you're a 14-year-old kid trying to wind up your parents, this is useless. For this tutorial, I'm gonna drop you from the seventh story into the deep end of the pool. I'm going to show you how to animate one of the more complicated controls. Mastering this control should at least make it easy to animate less complicated controls (in theory).
