What can I say? These icons are the most beautiful I have ever seen available on the Mac. I use them since 1988. ;) More beautiful than the ones by default in Jaguar. lol. With CandyBar, it's really easy to install them at their respective places.
By the way, the Utilities icon seems to be useless since the system refuse to let the user/admin replace its icon.
Let me know if you have a solution for the Utilities folder.
