M. C. Escher 2007 Calendar

The 3-D clutter on your desk may seem chaotic and puzzling, but it's nothing compared to the befuddling 2-D images by M. C. Escher in this desk cube calendar. Each weekday page reproduces a work in black and white (261 images) . Each weekend entry (Saturdays and Sundays share a page) features an excerpt from Escher's writings, accompanied by one of four repeating images.
