I am pretty floored by these photos, taken by Gary Greenberg using an extremely high-powered microscope, and showing what individual grains of sand from various beaches around the world really look like up close. The variety! The shapes and colors and patterns! This is exactly the kind of marriage of art, science, and the hidden astonishing world all around us that just inspires the heck out of me. Thanks to Beautiful/Decay for drawing my attention to these amazing images.
