The artists of rAndom International created a pretty impressive “rain room” at London’s Barbican arts center in 2012, incorporating 3d tracking cameras and a water management system to keep any visitor dry while walking through the rain.
“Rain Room is a hundred square metre field of falling water through which it is possible to walk, trusting that a path can be navigated, without being drenched in the process.
As you progress through the space the sound of water and a suggestion of moisture fill the air, before you are confronted by this carefully choreographed downpour that responds to your movements and presence.”
