meta-material is awsome stuff! read up on it and realize how crazy it is. imagine this... you know how light goes through water, reflecting a little off angle? well, if you had a "pool" of meta-material, and shone light through it, the i mage would appear floating above the pool... also, the dopplershift is reversed... instead of a train getting louder as it comes closer, meta-material gets softer as it gets closer and louder farther away!!!
