According to this article, Nasa is about to "conquer space with swarms of tiny robot pyramids":

The first steps have just been taken at the Goddard space flight centre in Maryland by an awkward robot creature called the Tetwalker hobbling across the floor of the lab.

Tet stands for tetrahedral: the prototype is an empty pyramid with four electric motors at each node linked to each other by six struts.

Tet can telescope the length of each strut, thus altering the robot's centre of gravity so it topples - enabling it by successive topples to move flip-flop fashion in any direction.

So, kinda like John Kerry, huh? (Cue hollow laughter.)

Another interesting article can be found here; a modern "devil's dictionary," containg many hilarious, and all too true, points like this:

Abuse n: Modern word for what was once referred to as torture. An interim term, soon to be replaced by "tough love" (which, in turn, is expected to be replaced by "freedom's caress").

And this:

Democracy n: 1. A product so extensively exported that the domestic supply is depleted. 2. When they vote for us. (See, tyranny: When they vote for someone else.)
