It appears to be that scientists are getting ever closer to creating a `real´ invisibility cloak, such as the one featured in the Harry Potter books:
Harry Potter's cloak it isn't, but scientists report the creation of two visible-light "invisibility cloak" prototypes that promise improved optics and cellphones and, yes, invisibility.
The microscopic devices aren't actually in a cloak at this point, but they do bend light around their surfaces, researchers headed by Xiang Zhang of the University of California-Berkeley say. The devices rely on metamaterials, specially structured materials that in these cases have surfaces dotted with holes smaller than the width of visible light waves, less than 0.00003 of an inch across, which smoothly shuttle light rays around them.

I really do not know about you guys, but that sounds so cool! Imagin being able to eavesdrop into any conversations you want! Or sneak onto a plane without having tickets! Or...what else could you do? I think that the sky is the limit, really.
Leave me a comment and let me know what YOU would do if you had one such device!
