Susanna Hertrich created this prototype Chrono-Shredder as part of a student design project.

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.

If you're interested in manufacturing the Chrono-Shredder, get in touch with Hertrich via her website.
