The artist, Buster Simpson, "wanted to address social and ecological concerns through a functional piece of art," explained Doug Lauen, spokesman for the Commission. The artist intends that after the privy's patrons, preferably homeless, have filled the hole, it will be moved from its outdoor location and replaced with a tree, which is said to benefit from the fertilizer. "The finished piece is not nearly so important as the consciousness-raising which comes from challenging people's assumptions about art, their own bodies, and the environment," said Lauen.
Considering that a portable toilet can be purchased for less than $500 and a tree can be planted for $10, the cost for the heightened consciousness comes to $9,490. In fact, had the Arts Commission not agreed to sponsor the project, Simpson says he was prepared to set the privy up as "guerilla art." In other words, at no cost to taxpayers.
