Until recently, invisibility cloaks were the stuff of private laboratories or fantasy novels. Now, engineers from Duke University have taken advantage of 3D printing technology to fabricate an obscuring device that is inexpensive and can be put together in just a few hours. The device resembles a perforated disc, and algorithms determine where holes in the plastic patter should be placed in order to deflect microwave beams and create the cloak. Led by Yaroslav Urzhumov, the team published their results in the online journal, Optic Letters.

US currency is already embarrassing and this new design for the $100 bill is not helping.

This may be worse than the horrible US passport.
