Then there's this one, which allows you to see the world as the inbred cousin the Cylons don't like to talk about.
The brainchild of design artists Anne Cleary and Denis Connelly, these "meta-perceptual" helmets are as simple in terms of design as they are complicated to explain when you're caught wearing one in a public restroom. By "placing peep-holes in the right places, then using mirrors to beam the light straight into your eyeballs," they allow one the opportunity to see the world in "hyper-stereo and wide peripheral visions," just like some of our differently-eyeballed animal friends. There's even one that simulates horse vision, which seems perfect for those with a My Little Pony / Japanese robot anime / Eyes Wide Shut triple combo fetish.
It's also a great way for making bathroom attendants even more unsettling than normal.
