Scientists have created a cloaking device that can reroute certain wavelengths of light, forcing them around objects like water flowing around boulders in a stream. To creatures or machines that see only in microwave light, the cloaked object would appear nearly invisible.
There is a video on YouTube showing this in action and it is pretty impressive.
Ok, granted it isn’t perfect but it is already pretty effective. Imagine a full outfit with this capability. Even though you could still see the person, it might be enough to escape detection at night and that opens all sorts of doors … there could be a rise in extra-marital affairs because the guilty parties could hide in closets more effectively.
