Japanese Men Perfect the Cloak of Invisibility Much to Japanese Women's Dismay

Japan's been tooling around with versions of invisibility cloaks for years now, but they seem to have finally perfected it. Theoretically. By using "left-handed metamaterials" to make electromagnetic control devices, researchers can generate lenses that either reflect no light or have a perfect focal point—the end result of which lets you create a perfect invisibility cloak to skulk around Tokyo with. If you're really interested in the physics of the situation, you can head over to Nikkeibp, but we're pretty sure the illustration above will explain the matter just fine. [Nikkeibp]
