Info found on web:

"Three concentrically orbiting bodies floating optically in a dense spatial field represent minutes, hours and seconds. The green outer body revolves once every hour, the larger blue body revolves once every twelve hours and the smallest body, white, once each minute. 

The effect is housed in a 9 1/2 inch black cube. 

An interesting optical phenomenon occurs as the inner body, representing seconds, appears not to orbit in a true circle but rather in elliptical variations, traveling at times directly towards one of the other planetary bodies only to veer off sharply in an angular path. 

The effect varies with the position of the other bodies and is most pronounced when they are farthest apart."
