For many of us, it may be raining outside but if you visit the Barbican you could find that it is raining inside too.
The Rain Room, developed by artists in London, uses special movement sensors to make sure visitors do not get wet despite "walking in the rain".
BBC London's arts correspondent Brenda Emmanus talks to artist Stuart Wood, who created the installation along with fellow former Royal College of Art students Hannes Koch and Florian Ortkrass.
