The team behind the Danish pavilion at the World Expo 2008 in Zaragoza, Spain consists of three Copenhagen-based firms — architects Spektrum Arkitekter, graphic agency Loop Associates and communications agency 2+1. The Danish pavilion houses Círculos de Agua (Circles in the Water), an exhibition about sustainable living and lasting solutions that echoes the World Expo 2008 theme of water and sustainability. Círculos de Agua highlights Danish technologies that have started out small yet have the potential to affect global change. The underlying message is that everything we do spreads like ripples through water. The World Expo runs till September 14, so it's not too late to see it.
