Warp Drive

Back in Jan 2000, SciAm had an article titled "Negative Energy, Wormholes and Warp Drive" where they described the method of creating a ring of negative energy that could potentially pull space together and allow you to "travel faster then the spread of light".

Slashdot was nice enough to point out that

recent calculations showed that if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring the warp drive could be powered by the energy of a mass as small as 500 kg

Gizmag also has a Oct 2012 article: Warp drive looks more promising than ever in recent NASA studies.

3-D Wall Display Thingy

Not sure exactly how to describe it...Hack a Day points out this very cool computer controlled walls whose blocks can flex in and out on servos.  (actually they are Styrofoam blocks mounted against the walls that move, but the effect is very cool.)
