This competition's full name is the International Science and Engineering Visualization Challenge, run by the National Science Foundation and the Journal Science. I have won a Semifinalist honor in the category Photography with this picture called "Four Dimensions".

In it we see radial spreads at three separate stages; before they start, during the initial stages of three-dimensional movement, and later on when the spread is much bigger. Therefore time, the fourth dimension, figures highly in this image, where different stages of the rapidly and radically changing spreads are juxtaposed.
