section of plant stem by rob’s lensonlife http://flic.kr/p/8UJWfi. A 100x unstained stacked view of a section through a plant stem - a common variety of Spiderwort -Tradescantia fluminensis - I actually like the slightly lit edge of the stem - gives a planet rotating in space sort of look although this has the transmitted light illuminating a boulder field of cells.
The simplest things God thought of can blow my socks off.
