Want a not-so-normal calendar? Try Chrono_Shredder. Designed by artist/designer Susanna Hertrich, the Chrono_Shredder is a modified paper shredder that shreds a date page every 24 hours. Great conversation piece, or a great way to mess up your home.

“The Chrono_Shredder is a device that makes past time tangible. It is a hybrid between calendar, clock and waste producing automaton. It has no on/off-button, thus it is unstoppable, just like time. It features the 365 days of the year represented on a paper-roll. The paper-roll is led through a hacked paper-shredder, which is programmed to use exactly 24 hours to shred one “day”.”

Some people just need a way to visualize how important time is, how it is slipping (or shredding) away every second.
