Scientists unveil invisibility cloak…

Well,  it’s not actually  a cloak a la a Harry Potter novel,  but a series of lenses which do offer  three-dimensional cloaking  without distortion.   It’s pretty damned cool,  isn’t it?   Even better,  they offer DIY instructions on a model which can be built for less than $100.

UPDATE:  Since YAHOO  pieces sometimes evaporate into the ether without notice,  here’s the story  from The Daily Mail,  which may have been the original piece anyway.
