Very cool. I wonder if anyone prints 360o photographs on spheres; like the world turned inside out.

And I've never seen a panoramic animation before, like the .gif in the second link. Seems to somehow make it easier to 'get' a 360o view better than from a still.

When we have heads up displays on contacts, giving yourself 360 degree vision is going to be interesting. They say the mind adapts to things like flipping the visual input upside down, so I wonder how much adaptation to 360 degree vision would happen.

By the way, could this cylindrical 360o thing be done optically?

I see what you did there. No, really.

So the method in the first couple links involves spherical and hyperbolic mirrors, and then reprojecting onto a cylinder, which is then cut and laid flat. (Obligatory Escher drawing) It's all done 'optically,' by pointing a standard camera at a mirror of a particular shape. They're using this with a mind towards computer vision; it makes for a (presumably) cheaper method to build a panoramic camera by requiring just a specially shaped mirror instead of heavily modified cameras, for example.
I guess for human use, I could imagine a mirror hanging above your head and some kind of parascope pointing up at the mirror, but it seems kinda impractical.
It's definitely something you can adapt to, and pretty quickly at that. If you run your favorite quake engine and type 'fov 120' in the console, you'll get a wider-than-normal field of vision, which you can adapt to very well. (It's considered cheating in gaming circles, from what I understand.) The last link contains a couple 'cleaner' plugins for Quake so you can play around with this yourself, and see what the effect on your brain is.
Helmholtz apparently made some sphere lenses to look at the world through, and said he adapted to the experience quite well. It's supposed to cause the world to look hyperbolic instead of Euclidean...

That shit was awesome. But then, I'm a math geek.

I have. And I've also wished that I could talk like Kurtis Blow, but that's neither here nor there.

And now I've learned that it's possible to animate the little favicon in FireFox. Blink tag 2.0!

kaibutsu: Somebody actually made a quake client that does a true fisheye projection of FOV. It is much more accurate than the stretching done by the original client.
