A paperclip isn't much of a step up from a human hair, but I suppose it makes you wonder if University studies are making headway in the matter, how much further along could other science groups be?

Invisibility Cloaking Using Calcite

Researchers have demonstrated an idea for an invisibility cloak using calcite, a common crystalline material. Cloaking relies on guiding light waves such that waves from a hidden object do not reach the eye. Calcite accomplishes this by sending the two "polarisations" of light - directions in which the light waves oscillate - in different directions.
