In an exploration of fictional tools for hibernators, Susanna Hertrich developed the Chrono_shredder, a product that serves as a reminder to live one's life productively. The 365-day calendar is dispensed day-by-day from a single roll, each day shredded over an exact 24-hour period.
The Chrono_Shredder's function is not to show the current moment, like a calendar. Instead, it shows the nearest future (the next day) - and all the time that has past from the time the device has been switched on. Whilst you spend your time in hibernation - the Chrono_Shredder messes up your space with wasted time!
