Pe Lang's Positioning Systems, from his Falling Objects collection, is bit of a curiosity -- it's a work of art that's equal parts printer and science experiment. A machine squeezes single drops of water onto an omniphobic surface, creating a 21 x 21 grid of tightly packed, but isolated beads of agua (that's 441 moist little spheres, for those of you keeping count). Slowly, over about five hours, the water evaporates and the process begins again, with each tick of the machine slowly reforming the square. Trust us, you want to see it in action after the break. Next, maybe Pe Lang can whip up evaporating images -- the Engadget logo would
look pretty sweet as a dot-matrix water print.
