P.S. Just to let you guys know... You might have realised that I'm not posting as much, I'm in India.. takes time to get to a net cafe, no other way of getting online, and the worst part is.. I'm stuck with crappy windoze machines! GAH!
 
Just for your information, a fine site for OS X icons is xicons.com. They have TONS of beautiful icons for just about anyting including replacement icons for apps!
