Mirrors Mirror creates the viewers' image by directing 768 small mirror tiles in a way that reflects different portions of their image. The piece is made of 24 columns of "pixels" that form a concaved curved surface that is aimed at the viewer. Brighter pixels reflect the upper body of the viewer and the wall behind him and dark ones are aimed lower. Artist Daniel Rozin will be featured in the Exploratorium's 2009 summer exhibition, Reflections.

Why do the hands on clocks go "clockwise?" Seems like a circular definition, but if you looked closely at sundials in the northern hemisphere, you'd notice that the shadow of the sun moves around the sundial in a "clockwise" direction. This was adopted by clock-makers and became the standard we know today.
In the southern hemisphere, the sun's shadow moves around the dial in the opposite direction, so if clocks had been invented there, our watches would move the other way.
