I've drawed these at school and re-did the job at home behind my iMac with WACOM tablet. If you like it, please comment. If you don't, GO AWAY!!!
It's just an idea. I dunno if I'm going to work this out in the future, but it's sure a good idea!
The icons are (from left to right):
Apple Logo normal, Apple Logo eaten, Finder, Mail, Dashboard, Safari, Addressbook, iChat, iTunes, iPhoto, iMovie, iDVD, GarageBand, iWeb, iCal, QuickTime, Photo Booth, Time Machine and System Preferences.
