Searching the web I came across the work of Dan Flavin. The bright colors and interesting shapes caught my eyes. Here is one of his pieces (http://www.nga.gov/exhibitions/2004/flavin/introduction/introduction.shtm).
I also came across the work of Ann Hamilton. There was a show called "At hand" where a large room became filled with white paper (printer-size). There were 6 machines that dropped the paper from the ceiling while a quiet voice spoke phrases (e.g., "a hand offers"). According to an article in the New York Times by Ken Johnson " the clicks, whirrs and sucking sounds of the machines, the pages fluttering to the floor and the voice interspersed with a low whistling sound all conspire to create an experience that is almost but not quite transporting" (http://query.nytimes.com/gst/fullpage.html?res=9C0DE3D8153AF930A15752C1A9679C8B63).
