Spanish artist Javier Riera has the ability to turn organic forms (mainly trees) into surreal, geometric structures. These structures float off the ground like alien ships or strange wrinkles in the fabric of spacetime. In reality, they're actually extremely simple, but the effect is quite striking. Riera uses light projections in the shape of geometric forms and projects them directly onto trees and other natural forms. The results are then photographed, so no digital retouching is used for any of the photos you see here. The projections are simply aimed at trees and powered on. The shape of the projections, along with the areas of darkness surrounding it, creates an optical illusion that makes it appear as if trees have corners, flat planes, and the ability to float over the ground.
