The search for the perfect invisibility cloak lumbers onward, but that lumbering is starting to pick up speed. We're hearing more and more these days about metamaterials, the possibilities of time cloaking, and other such future-stuff.

That is, no matter the angle of observation, the object was rendered invisible in 3D.
