New baseball card technology unveiled.

Scientists have created two new types of materials that can bend light the wrong way, creating the first step toward an invisibility cloaking device, according to Reuters newswire. One approach uses a type of fishnet of metal layers to reverse the direction of light, while another uses tiny silver wires, both at the nanoscale level. Both are so-called metamaterials -- artificially engineered structures that have properties not seen in nature, such as negative refractive index.

Dinged Corners has learned that one of the first uses of this new technology will be in manufacturing a baseball card called "Metamaterial Refractors." When held a certain way, the card will disappear, leaving only a shimmering autograph or piece of game used jersey, along with a 1/1 emblem--because every card will disappear in a slightly different way--visible to the naked eye.

We'd post a picture but until refined, it's possible the prototype card's incident ray's negative refractive index might make everyone's eyeballs explode. Thus we can show only a side view.
