Jamie Harkins is an artist in Mount Maunganui, New Zealand. As you can see from his Facebook gallery, he's a fine painter who creates canvases with vivid colors. But after seeing three dimensional chalk drawings on pavement, he felt inspired to try a different medium.
With the help of other artists named Lucia Lupf, David Rendu, and Constanza Nightingale, he created enormous sand images on local beaches. When viewed from certain angles, they appear to pop out of the surface of the beach. Harkins explained his goals to the New Zealand Herald:
"We've seen other people doing stuff on beaches, but it's always been geometric, flat shapes, like a pattern, so we thought we'd get into the whole 3D thing," he said. "And I kind of like the fact that it disappears at the end of the day when the tide comes in. It makes it impermanent."
