Speedy Enigma

Photo date: August 20, 2015. Photographer: Mark Mahin.

The photo below was taken indoors, and shows an ordinary featureless wall. We see what seems to be an orb that was moving very fast. The camera seems to have caught three different position states of a fast-moving object.  This creates a "string of pearls" effect similar to the effect shown in these 13 posts.

There were no insects observed when this photo was taken, nor were there any lights in the room other than the light of my camera flash.
