Solves the ages old problem of what to do with those calender days once they've been used.

The Chrono-Shredder is a device that reminds us of the preciousness of our lifetime. It represents the passing of time by shredding the days of the year – printed on a paper roll – at a slow constant rate. To shred one day takes 24 hours. There is no "off"-button. As the seconds pass by, the tattered remains of the past pile up under the device…

Brilliant!

Time gets shredded as it passes by.
