Defocusing LED Clock

[Dennis] has created a well-documented and very beautiful clock in his latest project. This clock stands out from the other clock projects we have covered with its unique display. The seven segment LED displays mounted on a sled that moves them back and forth behind an array of fiber optic lenses, effectively taking the display out of focus at certain points. Currently, a Dorkboard controls the sled, moving it at random intervals. The case is machined and polished aluminium, the top buttons are ball bearings.
