Barbican's Rain Room AARON COHEN · OCT 10 2012
Artists in the UK have created a 'Rain Room' inside the Barbican that gives the impression from the outside that it is pouring rain. 3D cameras make it so the rain stops when you walk through it. That is, the rain is everywhere you aren't, and you don't get wet at all.
Update: Neglected to mention the Rain Room is an installation by rAndom International artists Stuart Wood and Hannes Koch.
