If you do anything with web design you should check out Xyle.
It is a very cool tool for analyzing he style sheets of websites. The interface is awesome. My office mate, who doesn’t do any web stuff that I’m aware of said you should register just on the principal of it being so cool. I’m going to work with it some this weekend, but will probably pay the very reasonable $14.95.
And it is OSX only so if you are windows user you should look at the site just to eat your heart out.
