PHOTOS: The hidden beauty of sand

<div class="meta image-caption"><div class="origin-logo origin-image "><span></span></div><span class="caption-text">Sand hardly seems like the stuff of dazzling natural beauty - until you see it through Dr. Gary Greenberg&#39;s eyes. The images in his series &#34;Sand Grains&#34; are captured through a high-powered, unique light microscope, which transforms ordinary grains into works of art. Greenberg began his career as a photographer and filmmaker; he also earned a PH.D in biomedical research and went on to invent high-definition, three dimensional light microscopes.
