Mother Nature isn't the power behind these flowers—the colorful arrangements are actually composed of several soft polymer pillars used to measure the traction strength of cells, such as those that close wounds.
A fierce battle between the forces of surface adhesion and pillar stiffness threw the pillars against one another, forming accidental "flowers" that were imaged via a scanning electron microscope.
The image, taken by a University of North Carolina at Chapel Hill team, won an honorable mention in the 2009 International Science and Engineering Visualization Challenge.
