Sky Loom is an unrealized work, a seventeen-story-tall holographic glass light shaft integrated into the tower of a twenty-six-story mixed-use building once planned for the historic downtown of Albany, New York. The building housed a four-star hotel and a business and conference center whose presenting side faces north and is thus always in shadow. The artist solved this challenge by redirecting sunlight onto the north face and dispersing it into a spectral display using holographic glass. A heliostat (a microprocessor-driven mirror array) on the roof follows the sun throughout the day and season and redirects sunlight down the light shaft, where secondary mirrors reflect it into holographic dispersion gratings within the glass, creating an ever-changing pattern of colored threads visible from both interior and exterior.
