engineers have recently started the long march towards invisibility. a team at Duke University's Pratt School of Engineering have made a device (pictured) that can make an object invisible to microwaves. even though microwaves have a longer wavelength than light, this is a great start. they are only able to do it in a 2 dimensional form but 3D is probably not too far off. this article will lead you to the basic how's-and-what's involved.
