"Art installations revolving around the harnessing of kinetic energy may be old news, but Swing by Moradavaga, a design collection based in Porto and Berlin, has revived it in a playful way. As its title gives away, it is a swing set that generates power with every pump. This power is fed into a system of lights to illuminate the area at night. A playful and interactive installation, Swing by Moradavaga also provides a sense of gratification in regards to activity and environmental awareness. Created for the Pop Up Culture program promoted by Guimar&amp;atilde;es 2012 &amp;ndash; European Capital of Culture, Swing by Moradavaga was built outside of the International Centre for the Arts Jose de Guimar&amp;atilde;es. Each swing is attached to a bicycle chain that turns a wheel to power the lights."^^<http://www.w3.org/2001/XMLSchema#string>
