Binary Clock wins nerds over

Cracking your head over what to get that geeky, thick-glassed colleague of yours who goes on and on about quantum physics and how bounding boxes work in first person shooters? The Binary Clock could be the perfect solution to your conundrum, as it replaces the traditional numerical digits with actual binary codes from 1 to 12. Laypeople will just read the time like any other analog clock without cracking their cranium over converting those 0s and 1s. The Binary Clock comes with a 10″ diameter face and is powered by a single AA battery. At $40, it is expensive but you can never pay too high a price for novelty.
