British artist Andy Coutanche — nicknamed "Sandman" — hails from the isle of Jersey and works with a simple rake. His beaches are his ephemeral canvases. But while you may stumble on his work during a walk on the beaches of the Channel Island, you will only get the full picture with a bird's eye view. While waves ultimately devour the artworks, some are lost even before they are completed.

The German artist Luzius Ziermann leaves his signature only at selected places. And you'll only make it out from cloud level. Here, he assembled countless discarded car mirrors to create his inimitable mark in the ancient arena in the Italian city of Verona. His first signature installation in the desert of Namibia was so massive it could be seen from space.

Italian farmer Dario Gambarin has proved that anyone can be creative. He utilizes the time between sowing and harvesting to turn his field into a canvas. With his tractor, Gambarin "paints" portraits in his cornfields, like that of former US President Barack Obama. Here he also makes a play in the former president's "Hope" slogan, letting anyone flying over know his affinity for his land.

The models in the works of British photographer Joseph Ford tend to blend into the background. For his project, "Knitted Camouflage," he worked with a talented knitter who created oufits that blend in with his colorful, playful backdrops. For this massive rooftop smiley, an XXL sweater is worn by musician and acid house DJ, Fatboy Slim. But again, one only gets the full perspective from on high.

Briton Simon Beck likes to spend winter in the French Alps, but not so much for downhill runs and après-ski. Instead, Beck spends his days trudging through the deep ice with his snowshoes. Along the way he creates spectacular geometric shapes that he later photographs and shares on social media. Some of his works cover three football fields and are best viewed from the top of the mountain.
