PEOPLES: As promised below, I've re-drawn this so its now high resolution - you can download a 1920x1080 version here: [link]
Merry Christmas Everyone!
All done in Fireworks CS3, for it was the only thing working at the time!
EDIT - Welcome to people in 2008, nice to see this still getting recognised, Merry Christmas
EDIT - Welcome to people in 2009! Again, nice to still see people downloading and sharing. Since I've lost the master file for this years ago, I'm going to attempt to re-draw it again and make some new wallpaper sizes. (And also fix a mistake with the lighting!)
EDIT - Hello people in 2010! As promised last year, I did re-draw the file and you can download it here: [link]
