If the Bimota DB7R Diavolo Rosso is a bit much for your holiday wishlist, consider adding this equally overpriced holiday gift item. The Catena Wall Clock is a clever use of a bike chain and gears to tell the 24 hours in the day…well 12 hours in the day, you’ll have to figure out if its day or night on your own. A while we’d love to have one hanging in our office, the $2,338 price tag seems a bit much for what is essentially $20 in parts.
