From the article This is Your Brain on Yoga (click image for article) comes this example of gratuitous meshing in graphic design. Apparently, yoga meshes your brain. Thank you, alert reader Dan for this tip.

A Truly Fluid Mesh

Sometimes the fluid makes its own mesh, or at less polygons that look like mesh cells to me. The image below shows one particular result when a vertical jet of water impinges on a “circular horizontal impactor.” The shape and structure of the resulting sheet of water depend on a number of factors including speed of the jet and viscosity of the fluid. See a gallery of other results at the Fluid Polygons and Polyhedra page of MIT math professor John W.M. Bush.

Happy Independence Day to all our readers in the U.S.A. – or to use today’s vernacular, Usexit Day. (With apologies to our cousins across the Atlantic.)
