It is probably due to the recent WebGL policy of not admitting textures from a 
different domain. I think the security risk that triggered the policy is 
exaggerated but the standard has imposed the limitation anyway (cross domain 
images have been at the core of the Web almost always).

I guess systems like this one should add something like a tunneling mechanism 
in the server side that redirects requests to map providers so that textures 
seem to come from the same domain as the app. I don't think the standard method 
for allowing cross-domain textures is not usable here.

See 
http://hacks.mozilla.org/2011/06/cross-domain-webgl-textures-disabled-in-firefox
-5/

The cross-domain security restriction on WebGL textures also seems to apply in 
the current Chrome release.

Very annoying!

I too can not see the globe.
 I am using Win XP with Sp3 on Intel core 2 duo system with Intel GMA G31/33 chipset.
Graphics drivers are updated to the latest.

Other WebGL samples are running fine. But for this sample i don't see the globe.

The errors i see through inspect element in Chrome are:
uncaught error: could not initialize shaders - api.js : 1
failed to load resource
uncaught error: Cannot read property 'a' of null - api.js : 50

Thanks in advance.
