The famous Protrude Flow, permanently exhibited at the Ars Electronica Center in Linz, is one of the few spectacular electromagnet sculptures artworks. A black fluid reacts to sounds and voices, and assumes organic, three-dimensional shapes that grow counter to the force of gravity. An interactive installation in which fluid movements of physical materials evoke surreal impressions.
Morpho Towers, Two Standing Spirals is another work of this kind, built by Sachiko Kodama and Yasushi Miyajima, with music provided by Tetsuhide Hidaka. On the usual plate filled with the black fluid, two rotating helical spiral towers are able to spring up trembling magnetic fluid spikes, moving in synch with the music, thanks to finely tuned magnetic fields. The synch with music is accomplished through metadata, so the liquid somehow, embodies the music presence and movement. The same fluid is able to trick gravity, and it represent a liquid materiality triggered by magnetic invisible fields. So the immaterial (digital) communicates with the invisible (magnetic field) generating a temporary material embodiment (the magnetic fluid spikes).
