James H. gets a high-performance no-prize for bringing us news of one of the coolest submarines ever:

The machine is capable of performing the same tricks as living dolphins, including dives, barrel rolls, jumping in and out of water and "porpoising". It can even roll to one side and wave a flipper.

With a top surface speed of almost 50km/h and an underwater speed of 32km/h, the dolphin is made of fibreglass and Kevlar and is fitted with a watertight F-16 fighter jet canopy.

To which I thought to myself, "yeah, right." Except there's a picture of the thing with the article. What a nifty way to get yourself killed!
