Here's what happens when you dip a wire cube into soap solution; the soap makes multiple membranes, then all the membranes try to figure out a configuration where everything is under the least amount of tension.
Hmmm. I wonder... if you made the wire frame electric, could you make the membrane a kind of analog computer? If you knew the capacitance of the soap solution, the wire could be a series of resistors.
Oh well. It looks cool, anyway; although the room the frame was in smelled like it was stuffed full of microscopic flakes of detergent.
