[math-fun] Computing with water droplets

This might make a nice fountain. --Rich --- http://www.sciencedaily.com/releases/2012/09/120907082027.htm Towards Computing With Water Droplets: Superhydrophobic Droplet Logic ScienceDaily (Sep. 7, 2012) ? Researchers in Aalto University have developed a new concept for computing, using water droplets as bits of digital information. This was enabled by the discovery that upon collision with each other on a highly water-repellent surface, two water droplets rebound like billiard balls. http://www.geekosystem.com/water-drop-computing/ [an ad-heavy page, but includes a decent video of a 1-bit counter]
