Cloaking devices are here, provided you are already invisible

National Geographic on new cloaking research:
Both materials still have a long way to go before they're ready for stealth military operations. To start with, both cloaks work only in infrared light for now. The next step is to try to develop a version that works in visible wavelengths. The cloaks are also capable of hiding only microscopic objects.

    The cloak that makes you invisible while you’re walking around is not going to work. For a very long time.

    The invisibility cloak you hide behind while leaning on a tree, or on the ground (like we see in ninja cartoons) is within reach already. In the hi-tech version, it’s a large human sized e-ink paper/cloth. A nearby camera looks at the cloak, and modifies the displayed scene to make it merge into the background.
