Warm theme with custom Naruto background. Contact me if you want the SVG version of Naruto from the background. Trees were from the OpenClipartLibrary (I'd get the author's name, but OCL is being upgraded and the search page is erroring out, I'll edit this with it later) The foreground is completely custom artwork done in Inkscape. "Naruto" logo is simply a vectorized copy of the original logo.
The theme itself is based on the Ubuntu GDM theme, with the same GTK settings (more because I'm too lazy to make my own). Background is based on a wallpaper I found about a month ago that I really liked - but it was under a "no-share" license, so I drew my own.
The font is "Ninja Naruto" (included, as the license allows it) - make sure you install it properly.
I *may* change some colors around and make a "Part II" version, if I have time.
edit: Alright, got the info on the guy who made the trees: Username on OCAL is "Chrisdesign", the tree silhouettes were released into the public domain. ;)
