Tatty Devine is a London purveyor of jewelry and accessories, who sells this interesting curio, a 3-D glasses necklace. Not just another pretty necklace, this is a real, functioning pair of anaglyph 3D glasses. It is made to resemble a cardboard pair, but it's really fashioned of acrylic and metal.

It's a neat idea, but they only come in red/green variety, which severely limits their usefulness. The high price (45 pounds) is another impediment. Still, I am encouraged to see 3-D glasses becoming so fashionable, even if in a postmodern ironic way.
