News: Zooming Into Sand

Incredible. There's a type of sand (found only on the small Okinawan island of Iriomote) in which each grain resembles a tiny star. And I never would have known, if it hadn't been for blogger Jason Kottke's pal Mouser. Mouser collects sand from all around the world, and then documents each sample with a macro lens:

Zooming Into Sand — Star sand, found only on a few beaches in southern Japan, made of "the calcified shells of tiny organisms only a few milimeters across."
