Neto's work, Nave Nove, is part of the Tiroche DeLeon Collection and is created out of a white stocking-like material. The Brazilian artist often fills his sculptures with styrofoam or spices. This particular piece was intended to allow visitors to walk through it and put hands through the sides (near the end of the video).
Martiel's piece, DIctatura, was part of Time Sensitive-Pinta Projects and examines the grip dictatorship has often had on Latin America. A man is chained, by his neck, completely nude, completely exposed, to a flagpole. The man is the artist himself and the performance continued throughout the fair. The flags of 21 nations went up that flagpole--each nations that have been (or currently are) dictatorships. Some of these dictatorships were themselves "sponsored" by the School of the Americas.
