The image of the GNU was done by the Nevrax Design Team and is available at:
http://www.gnu.org/graphics/meditate.html

the background (behind the gnu in the bubble) was done by dsaguto, and is available here:
http://art.gnome.org/backgrounds/gnome/1076

Basically, this was just a small project to show how cool it is when artwork is GPL'ed. I'm sorry that i don't have the bandwidth to host the 2.9 Meg .xcf GIMP file, if any one wants it, i would be happy to email it to you - drop me a line at:
