In the interactive art installation “Rain Room,” visitors can walk through a thousand square foot space that is being soaked by falling water—without getting wet themselves (video). To achieve the effect, cameras track the locations of people within the installation, shutting off nearby water valves to stop the downpour over the visitors. The installation is on display at the Barbican Centre in London through March 3, 2013. “Rain Room” was created by London art studio rAndom International.
