CBSnews.com has this story on a piece by Carsten Holler that was installed Monday at the Tate Modern in London.
The New York Times has more, including the following quote from one of the curators, who calls the installation “participation art”: “Holler firmly believes that slides should be far more widely used in public life. The idea is that if we all went down a slide on a daily basis, it might profoundly change our lives.” The tallest of the slides is 182 feet long and deposits its passengers 87 feet from the top floor of the building.
