Empire consisted of a four-screen continuous surround animation of a virtual monument running the "course of empire." It is inspired by the 1836 paintings of Hudson River School artist Thomas Cole's series. Empire slowly decays and molds as it transits from sunrise to sunset. This piece uses a cenotaph drawn by Étienne-Louis Boullée the 18th-century French visionary architect as its source. It slowly decays and morphs from pink to blue, from sunrise to sunset. Camera motion is a slow zoom, direction z.
