Engineers create 'optical cloaking' design for invisibility

This is pretty wild- the idea is to bend light around an object such that the observer sees the projected image of the backgound instead of the object being cloaked. The invisibility cape is coming! Ok, so it still only works on one wavelength of light (namely red today), but they are working on a version which will work on all visible wavelengths. They say it is theoretically possible and that the size of the cloaking could be arbitrarily large - the size of a person or aircraft for example. How cool would it be to be able to cloak skyscrapers or power lines? Now, if they could only just work on getting the Star Trek transporter to work...
