TAKE IT WITH A GRAIN OF SAND
When you walk along the beach, how often do you think about the sand between your toes?
If you get close enough, each grain can reveal incredible shapes, sizes and colours; each an artwork in itself.
These images of grains of sand from around the world were taken by photographer Dr. Gary Greenberg using an Edge 3D microscope. The full collection is published in his book, A Grain of Sand.
