8 components each 6'W x 8'H, all supporting 7 blades @ 18" x 10', all constructed on each wall one above another in increasing 15° increments. These blades are fabricated from 3/16" Implex, over laminated with a mirrorized bidirectional diffraction grating which reflect rainbows, day and night, in different hues, wrapping around upper corner, at building's entrance.
