Disturbance

Disturbance in the Force Field

No, not a fancy science fiction image. This really is just what the title says. The field that was disturbed is the surface of the water in a small creek. It is a water strider, a small insect, that provides the disturbance. The tiny creature is covered, especially on its legs, with tiny hairs. These, like wax, are not wetted by water. The water’s surface tension provides the insect a resilient surface on which to propel itself with rowing motions of its forward legs. Little ripples form around the tiny creature as it moves about. It is those ripples that are imaged in the original photo that is the basis of this café art manipulation.

The Bog

A Southern Bog

If you every seek a place that is totally confusing, frightening, disorienting, come to our Southern swamps and bogs. These are places where you can hardly tell the reflections from reality, safe paths from instant disaster. And yet, they are captivating. The image shows vines, tree trunks, small plants and a little bit of open water from recent rain. A few more weeks and this place will be totally obscured by the growth and leaves. The water surface will probably turn green from algae and aquatic plants. Then again, the place may dry up and present a squishy ground until the next rain. Bogs are that way.
