Moss under a Microscope

Moss from a path in my garden under a microscope with grains of fine sand. This photo was taken with a USB microscope I bought from Adafruit that I used to inspect circuit boards.

My father has now adopted it as it turns out it is brilliant for looking at postage stamps for the little differences that philatelists need to spot. All his friends at his stamp club have been buying USB microscopes since he showed them. Better to look at a nice large screen than squint through a magnifying glass...
