Amazing Large-scale Drawings in Sand by Jim Denevan

this guy, who is an artist and a surfer, creates large scale drawings in sand that are nothing short of amazing. The drawings are mostly created by dragging a stick on the ground. By using only this single stick of wood wet, Jim Denevan makes huge geometric shapes in the sand, which for some may take up to seven hours of work! Generally composed of circles and lines, it is a real mammoth task and patience.
