The flush: "Don't Miss a Sec" toilet

The lowdown: Venice-born artist Monica Bonvicini would have us believe her roving installation titled Don't Miss a Sec is a commentary on the reluctance of art fans to miss even a split second of an exhibit. Perhaps, but what it looks like to us—and to anyone walking by outside on the street—is a mirrored silver box. Once you're inside, you can see the rest of the world through what appears to be clear glass—no surprise that you'll likely be praying that the one-way mirror actually works. (Shy types might opt for more traditional options—say, a restaurant nearby.) The work debuted as a public loo across the street from London's Tate Britain in 2003 and was exhibited at Kunsthaus gallery in Zurich last summer. Its next public appearance has not yet been decided. But if you see a giant silver box in a public space, point and laugh as you pass—a cruel but fun way of freaking out whomever is inside.
