About The Cover

Three-dimensional microstructures were formed by contact printing a pattern on metal-coated glass capillaries (~2 millimeters in diameter), then etching the unprotected metal, electroplating onto the remaining metal structure, and subsequently dissolving the capillaries. Pulling the microstructure at both ends transforms its symmetry from cylindrical (middle) to fully three-dimensional (remaining structures). The structures were imaged through a stereoscope.
