German designer Susanna Hertrich's Chrono Shredder is "a hybrid between calendar, clock, and waste-producing automaton," that has no on/off functionality. It runs unstoppable for 365 days until it has continuously shredded all of its calendar pages, which are kept on a paper roll. The paper is fed through a hacked paper shredder, which is programmed to use exactly 24 hours to shred one "day." The device reminds us not only of the day, but of the passing of time. So, on Dec. 31, you'll have a big pile of shredded paper that is not simply waste, but actual evidence that time has passed. Hertrich created Chrono Shredder to target would-be future hibernation obsessives, to remind them that while they sleep, something tangible is happening. The design is not actually in production. Would you like it to be?
