I get this effect often during 3D modeling, when I'm looking at a wireframe in perspective. Sometimes my brain inverts the perspective, and I have to mentally invert the view again. Funny effect, always makes me smile.
This thing is so neat. I printed out and made one of my own. Wonderful little device to have sitting on your desk The only problem is that you have to close one eye while looking at it. Great fun.
