If you enjoy watching paint dry, then you'd be thrilled to get your paws on Thorsten Streichardt's Rasen shredder. It's been modified to operate at a severe fraction of its normal speed, closely matching the pace of growing grass. Rasen shreds less than 1 cm of paper over the course of 24 hours, so don't hold your breath. (If it's shred-tastic entertainment you seek, you might want to invest in a hamster or two.)
