Can you guess what this is? Besides pretty.
How about this stuff? Hint – it’s underfoot.
This stuff is actually sand, magnified 250x. Sand, of course, not being an entity of itself, but a mix of bits of worn down shells, glass, minerals, skeletons…
Dr. Gary Greenberg of Sandgrains.com takes photos of sand and even has a book of photos.
These are making the rounds on the Internet, but I think are worth sharing again, just for their sheer beauty.
