I can't really tell you why I'd need a real paper calendar. Between my Droid and the computer, a printed calendar is a very un-green indulgence, but this one was created by British graphic designer Derek Bowers for the 2011 Pantone calendar. The color wheel contains a mosaic of 1440 graphic images with visual and cultural references. It's not offered for sale yet, but when it's out I'll have a hard time resisting.
