Japan's National Maritime Research Institute has developed a machine that can manipulate the shape of water so precisely that you would be forgiven for thinking you're looking at CGI effects from James Cameron's The Abyss.
During a recent demonstration to the media, the machine, originally designed as a water safety device, easily changes the shape of water into a heart, a star, and even a musical note. Sure the current applications for such technology are few, but anytime special effects enter the real world, it's cause for a bit of geek-out-joy. You can see video of the amazing water dynamic here.
