Combining art, science and a considerable amount of imagination and spectacle, Brighton-based The Dream Engine brings its aerobatic show Heliosphere to the WOMADelaide sky. The spiralling, spinning and seemingly weightless acrobats fly suspended beneath an enormous helium balloon, interacting with the world below, swooping to ground level and then soaring 20 metres in the sky in a matter of moments. The ground crew, harnessed to lines but largely unseen, control the balloons’ speed, direction and height, working with the artists to create magic. Music, creative lighting effects and ingenious mechanisms help realise the illusion of flight and levitation. Formed in 1998, last seen at WOMADelaide in 2006, The Dream Engine has performed in 67 countries and averages around 60 shows per year.
