The latest installation by Nils Völker in Austria features 1000 fans and 96 bags which inflate and deflate in rhythms controlled by an Arduino board. Every bag is controlled independently, forming wavelike gyrations along the wall. Creative Applications points out that it gives the installation the appearance of a pixels.
Inside each module there are eight cpu cooling fans inflating and deflating each bag in variable speeds… Although each bag is mounted in a stationary position, the sequences of inflation and deflation create the impression of movements. Forms appear from the net-like matrix and disappear back into the surface.
