I admit it, the title is mathematically incorrect. And I don't care.
You should care, however, about the three new wallpapers available here. If you're looking for a way to celebrate your D20 love, be it D&D, Pathfinder, or any other system that makes use of this beautiful die, then you it to your desktop to download these wallpapers.
Might I suggest using all three in slideshow mode? Cuz it's awesome that way.
