Sky Mirror

Sky Mirror

2009 – 2015

The color of the sky varies depending on the density of the atmosphere. Sunlight from the horizon travels through about 38 times more air than light streaming down from the zenith. Sky Mirror allows visitors to compare patches of sky from different altitudes, revealing the surprising range of shades and hues in what often seems a uniformly blue dome.
