Scientists one more step closer to realising invisible technology:

Until now, scientists could only make objects appear invisible from far away. Liverpool mathematician Dr Sebastien Guenneau, together with Dr Frederic Zolla and Professor Andre Nicolet from the University of Marseille, have proven -- using a specially designed computer model called GETDP -- that objects can also be made to appear invisible from close range when light travels in waves rather than beams.

Scientists predict that metamaterials could be of use in military technology, such as in the construction of fighter jets and submarines, but it will be some years before invisibility cloaks can be developed for human beings.
