From the excellent Etsy shop "Stuff Made From Stuff" comes this Recycled Tape Reel clock, made from an old school magnetic tape reel. The seven-inch diameter clock, which comes complete with a new quartz drive and a single AA battery, makes a great conversation piece or a perfect gift for a green-minded, geeky, and/or audiophile friend.
Check around the shop, there are clocks made from computer motherboards, keyboards, bicycle cranks, and more. If you see another set of clock hands on another clock you like better, they'll customize it for you. Also, if you have old electronics to get rid of, they'll make you a deal. Sweet.
