However try as a I might I could not cross my eyes enough to see it in all its glory. So I copied* the code and made the size of of the globes configurable (well I first tried just changing the hardcoded value), and the result is:

stereo-earth.php?s=200

I found I can get it to work on 200pixels, any bigger and just couldnt manage it, but try it yourself (change the numbers in the url).

Another tip: press F11 to remove distracting screen clutter.

* The original Google demo is under the Apache licence, so assume the Stereoscopic version is too, so this one is also, although the PHP is rather boring.
