Sundial with "artificial sun"

Last year, David Friedman proposed the concept of hours, which work in a similar solar, only instead of sunlight to be used light bulbs, rotating in a circle. Now Evilmadscientist.com craftsmen to make it a reality, with its largely improved. The resulting clocks operate on the principle of solar but reported time with a higher accuracy - down to minutes and seconds, as well as a light source using LED-bulbs arranged in a circle at three different heights. At any given time in each circle, only one lamp lights up, the result is a shade of three different lengths, showing the hours, minutes and seconds. Well, for additional visual effects used light bulbs in three colors - red, green and blue. The main components for the creation of such a clock - plywood for the base, 36 LED-lights and the necessary electronics.
