Hey that's a cool link man.
I love that stuff.

I was just working on something similar, to try and get the blur effect that Vista has. I've found a few ways to make only certain areas transparent, like Vista, so within no time I should have a decent aero example for XP users. Although right now my ATI tv tuner doesn't agree with it.
I think I'm cramping it's style. lol

Until then...
