The latest in invisibility cloaks

And, for a change, I didn't find this in HS Daily Wire, my usual source for cool weird stuff. This comes from Technology Review:

In effect, an invisibility cloak creates the illusion of free space. This is possible because of a new generation of artificial materials called metamaterials that can, in principle at least, steer light in any way imaginable.

Now Che Chan and pals from the Hong Kong University of Science and Technology say that metamaterials could be used for an even more exotic effect: for cloaks that create the illusion that a different object is present.
