Ok, I tried my hand at creating a bootanimation file. Being from Boston originally, I have customized my phone to be basically a member of RSN, so I needed the right bootanimation sequence.
I have created a boot animation of Dustin Pedroia's 2 run HR he hit against the New York Yankees at Fenway park on 6 April, and if anybody is interested it can be downloaded from here:

I have also customized my boot loading screen from the Motorola "M" to a trilogy of the logos from the Red Sox, the Patriots, and University of Michigan.
a sample image from the animation is attached, as is the boot loading screen logo.
