ATF Headquarters, Washington DC 

Water running down stainless steel cables fills a series of aluminum channels. The channels are supported by ball bearing so that they can tip. As each channel fills with water, it must “decide” to tip either left or right and spill water into either of the two channels below. Thus the entire array becomes an interrelated web of water decisions. The artwork is a prototype for a surface treatment on a cooling tower in Singapore at the Marina Bay Sands that is currently under construction. At night, lights bouncing off of the water will animate the facade with shifting patterns of shadows from the tilting channels. The artwork was installed in 2008.
