The poetic dimension of light in nature has always directed my eyes skywards.  Its changes at different seasons and parts of the day exert great influence on a person's mood and awareness of time and space. 
I wanted to create an optical element evocative of the sun's eerie lightshow near the earth's magnetic poles. the aurora.  Both the piece and the phenomenon reflect my interest the underlying structure that gives rise to aesthetic beauty.
AUROREAL is an example of diffraction: when light waves pass a narrow grating, they spread into well-defined directions: a spectrum.  In addition to being a major component in holography and optics, peacock feathers and butterfly wings owe their shimmering color to diffraction.
