Leslie Tonkonow Artworks + Projects is presenting sculptures by Agnes Denes (Nov. 15, 2012 — Jan. 19, 2013).

The exhibition, Sculptures of the Mind: 1968 to Now, includes “Human Dust” — a bowl of real cremated human remains. “Dust that strives to perpetuate itself,” is how Ms. Denes put it. Sounds like U.S. foreign (and domestic) policy.
