Engineers Devise Invisibility Shield

Posted by timothy on from the impossibly-large-yellow-somethings dept.

GerritHoll points out an article in Nature according to which "researchers at the University of Pennsylvania 'say that a "plasmonic cover" could render objects "nearly invisible to an observer.' Earlier attempts at invisibility worked by colouring a screen to match its background, like a chameleon. The described technique is new, because it works by the concept of reducing light scattering. It is not a 'magic cloak,' however, because it will not work for the full range of visible light and needs to be adjusted precisely for the shape of the object. However, the concept could find an application in stealth technology."

    +0 since it provides invisiblity only. Now, if you made it from scratch and had good rolls, you could have a cloak with invisibilty, +5 AC, saving throws, and AC.

    I'm refering to the real D&D: the basic system. AD&D is good but too complex and d20 is like EverCrack on crack.

    There are so many virus definitions out there these days that occasionally hotmail rejects one of my clean attachments because the binary code in the archived attachment accidently happens to have a virus definition in it.

    Yes, it is that bad.
