Artist Monica Bonvicini created this minimalist glass cube containing a usable loo to stand opposite the Tate Britain gallery in London.The work, called Don't Miss A Sec, is made out of one-way glass which means you can see out but not in. The public sculpture was exposed at the former Royal Army Medical College in Millbank, and was meant for public use. A spokeswoman for the project said: "It will arouse curiosity because people can just come and use it, although there is a question of whether people will feel comfortable doing so." The toilet was also exhibited at the Messeplatz in Basel, Switzerland, in 2004.
