Just saw a wonderful exhibit at the Geffen which included an installation with an interactive swimming pool! You could swim in the pool- as long as you wore a bathing suit. I didn't happen to have one handy but I was delighted to learn you could purchase a paper one in the gift shop. Inside a John Cage sound and light display while wearing my paper suit, I was able to experience the piece as the artist intended. It was a memorable art moment to be sure- even though the 'pool' was only about 5M across. To 'real' swimmers, that's hardly worth getting your hair wet! But in this case I was willing to make the sacrifice for Art.
