Click and drag to rotate the stereoscopic wireframe! For maximum 'whoa' value, 'spin' it with the 'spin' buttons, or play with the perspective and appearant distance.
'Stereoscopic' is a word that describes a way of generating images that appear 3-dimensional by having two different images, each with a slightly different perspective. One image is viewed by the left eye, the other by the right.
This wireframe applet employs the same stereoscopic technique as the old 3-d movies, which is to provide one color of image for one eye, and another color for the other. The other eye's image is filtered out by a coloured lens.
The old ViewMaster was a stereoscopic imaging device, based on a very old device known as the stereo-opticon. This was simply two lenses held at a distance from two images, in such a way as to focus each eye on a separate image.

Here's the globe in a non-stereoscopic context, for those of you who can't find your blue-and-red-glasses.
