Of course, this is a neat trick, but is it actually useful? In fact, Che Te Chan, one of the physicists working on the project, has indicated that the research could potentially mean that devices could be built that, when placed on walls, allow the viewer to look through the opaque material. There are, of course, many engineering challenges before these peeping tom devices (along with invisibility cloaks) will actually be built, but it appears that it may actually be only a matter of time.
