video Optical Illusion LED Time Table
Bend time to your will with this fun illuminated clock table!  The diffuser creates an illusion where time itself seems to twist and churn as you look at it.  The LED ring makes it look as if there is a laser pyramid rising from the table top... except that when you reach for it it flips around and dives inward just beyond your grasp.  You have never seen a clock like this before.
