"Binary Wall Clock Once upon a time only the true geeks amongst us were interested in buying a binary clock but the new Powers of 2 XLD wall clock - with its super slick design overhaul - is quickly becoming the must-have timepiece for 2007. Take a look at this gently undulating set of LEDs – nothing? It’s actually telling the time in binary, the language of computers. With a few minutes practice it’s simple to read, just by adding the values of the lights. The beautiful flat-profile, matte black clock will have the design-conscious clamoring to get their hands on one.
