I'd like to make a minor correction to the text of the otherwise well-written io9 article. The paragraph
"Metamaterials are materials engineered to do things nature didn't intend them to do. The most commonly built kind of metamaterials are "optically active" metamaterials, or materials that make light behave in strange ways."
might be interpreted to suggest that only metamaterials have strange or interesting optical effects, but that's not true.
Most organic molecules are optically active, as are some ordinary crystal-like substances. Dichroism, enantiomerism, and the Faraday effect are just some examples of "strange" optical phenomena that appear in relatively common substances.
@Roklimber: Great point. This is only meant to explain that the most common uses for metamaterials are goofy optics, not that nature didn't intend goofy optics. Thanks for the kind words about the article!
@twDarkflame: You're in luck. We're having a special on that just in time for Christmas. Supplies are limited, though, so place your order quickly if you want Dec 24th delivery.
@GalileoAce: Sorry, it's not a technical term! I just meant that it seems sudden when you hit a certain angle with respect to the cat's eye and all of a sudden it's glowing at you.

In my capacity as an annoying pedant, I feel I need to point out that nature has no intentions.

It's true because TV says so!
