This Clock Will Only Reveal The Time At A Certain Angle (Video)
J.P. Meulendijks' Mocap clock will only show you the time at the perfect angle. The numbers on the clock's face are actually made of small white dots mounted to black pins at varying heights. When viewed head on you can make out every character. But if you're looking at it from the side, all you'll see are just dots.
Not a bad concept, but it also comes with a heavy price tag: $247. [Plankton via PSFK]
