Robert Gober's "Untitled", 1997.

At first glance, Gober’s Untitled (1997), in the Milwaukee Art Museum, seems to be simply an open suitcase on the floor. Upon further examination, however, the bottom of the suitcase opens to a small installation beneath the museum floor featuring seaweed, coins and running water.

What does it mean? That's up to you. I've got more interesting shots from my museum visit in September. Watch for them.
