Lava Burst Street Art by Edgar Mueller

This giant fissure was created in the German town of Geldern by Edgar Mueller to celebrate the 30th anniversary of a street art competition. He spent five days, working 12 hours a day, to create the 250 square metre image of the crevasse, which, viewed from the correct angle, appears to be 3D. He then persuaded passers-by to complete the illusion by pretending the gaping hole was real.
