Denver has spent a fortune on public art, but it hasn't always gotten its money's worth -- with the latest sorry example being Jonathan Borofsky's "The Dancers," which cost more than $1.5 million. Once in a while, though, the city picks up a bargain such as "Fire House," which internationally renowned New York conceptual artist Dennis Oppenheim created for just over $40,000. The aluminum-and-acrylic sculpture depicts a house held aloft by ladders; a lighting system conveys the idea that it's on fire. The conflagration of imagery is unusual, but perfect for such a site-specific piece.
