441 Drops of Water, Neatly Arranged by Machine

It’s mesmerizing to watch Pe Lang‘s mechanical artwork in motion, especially this machine that arranges droplets of water on an omniphobic surface. From Triangulation:

Falling objects – positioning systems from 2009-2011 is a custom made machine that adds drops of water onto a special textured surface. Each drop forms into an almost perfect sphere through the surface tension of the water and the omniphobic material. The electronically controlled pipette wanders through a square grid of 21 x 21 drops to form a micro-matrix and returns to the beginning. After approximately 300 minutes, and when the water drops have evaporated, the same process starts again.
