Movies such as Predator have long shown off in science fiction fashion (no pun intended) the concept of an invisibility cloak.  Not only have they made a prototype in Japan recently but there may be advancements in the technology:

Now, researchers at Boston University and Tufts University claim that they have come up with an invisibility cloak that works within the terahertz band – the radiation between infrared and radio wavelengths – but could be modified to work with visible light. Intriguingly, it is made out of silk.

Such invisibility cloaks rely on metamaterials, which are a class of material engineered to produce properties that don’t occur naturally.
