Who thinks the folder icons are too boring, can change these fast and easy. Click the icon you want to change once, and blend in the information with apple-I. Do the same with the new icon, and click in the infoscreen on the icon. With apple-C you copy the icon, click on the icon you want to change in the infoscreen and paste it with apple-V. Because of an error in older OS X Versions you cannot change the icon again after this, but with OS X 10.3 (Panther) this is possible again.

Who is looking for new icons for his programs and folders, will find them on the site xicons.com. To make icons yourself, the Shareware program Iconographer is a good choice.
