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.
