Custom clock pays homage to CPU, separates geeks from the squares (video)

Pop quiz: Can you tell what the device pictured above is? If you answered "a clock that represents the essential building blocks of a CPU while using binary and HEX numerals to display time," then you're certifiably crazy -- and correct. The brainchild of tinkerer extraordinaire Lior Elazary, the "CPU clock" mechanically emulates the application of computer concepts -- codes, instructions and checks -- to create a "simple" wall clock. To display the time, the middle register uses binary numbers to indicate the hour (a reading of "0010" indicates 2 o'clock, for example). For minutes, the clock uses the HEX numerals on the outer edge of the device, so "05" represents "5," "0A" indicates "10," and so forth. Keeping the clock up to date is a ball that goes around and activates the various levers to change the time. Given all its geeky goodness, this one easily takes the nerd cake from the wordy QLOCKTWO W and super flashy Sci-Fi watch.
