Pe Lang's positioning systems - falling objects shows 441 water drops arranged on omniphobic material.
Great video of an installation by Pe Lang, positioning systems - falling objects. In the video, a custom made machine adds drops of water onto a special textured surface, forming an almost perfect sphere. The electronically controlled pipette creates a grid of 21 x 21 drops and repeats once the droplets evaporate.
