The National Maritime Research Institute of Japan has developed a machine that can create shapes in a pool of water, including a heart and a star. But that's just to entertain reporters. The primary purpose of the machine is apparently to conduct tests for water safety. At the link, you can view a Japanese-language video about the device.

Now if only they can make those water-tunnels from Myst II.

Eventually we're going to need a "New World Order" type of governing body to deliberate on global standards. The U.N. is the obvious choice for such a force but most of us countries who make up the U.N. are....well....we're kind of A******s.
Can we just elect Japan? I'm being kind of sarcastic but seriously, they don't seem to be concerned with beating anybody up (anymore) or robbing anyone, they just spend all of their time being entertainingly strange and making cool stuff.
And exactly what kind of still image would you recommend that does not freeze the action?
