Art- Reno Federal Building

This is the "cheese-grater-art-thingie" It was actually inspired by an old indian artifact found by the artist's father... I think.
From http://www.onlinenevada.org/michael_heizer :
However, Heizer has always worked on more traditionally scaled sculpture, painting, and drawing. In 1997, the General Services Administration (GSA) commissioned him to provide a sculpture for the narrow garden area in front of the Bruce R. Thompson Federal Courthouse at South Virginia and Liberty streets in Reno, Nevada, and selected Heizer's Perforated Object #27. Among the objects found by Dr. Robert Heizer's team during their 1936 excavation of Humboldt Cave is a curious piece of bone generally shaped like a fish—4.6 by 1.7 inches, it is drilled with ninety one-quarter-inch holes, with no explanation ever found for its use or meaning. The bone inspired Perforated Object #27. The weathered steel structure, 9.75 feet high by 27 feet long and 3.33 feet wide, is mounted at a ninety-degree angle to the tall, formal, grid-designed white marble structure behind it. The GSA's Reno community advisory committee asked for a smaller, second work for the rear of the building—a series of weathered steel rings representing the holes from Perforated Object. Initial public reaction to Perforated Object was negative.
