Just as the leaves of a tree define its volume and shape, this piece relies on approximately 7,000 multi-colored aluminum elements to define a soft, undulating volume on the south side of this hospital parking structure. As in nature, the volume and shade offered by the piece shies away from harsh, geometric patterning, instead tending towards a gentle, dappled variability in form. The effect produced by an articulated east/west color strategy creates a dynamic facade piece that offers observers a different visual experience depending on their vantage point and the pace at which they are moving through the site. In this way, pedestrians and slow moving vehicles within close proximity to the hospital experience a noticeable, dappled shift in color and transparency as they move across the hospital grounds, while motorists driving along Michigan Street will experience a faster, gradient color shift which changes depending on their direction of travel.
