I just explored the Google labs 3D body using the Chrome 9 beta and Firefox 4 beta browsers. I have not tried the Mac Webkit which needs to be enabled on the command line. Apparently Microsoft Explorer 9 team does not intend to support WebGL which is a bummer because such a large percentage of users are on MS Internet explorer. It would be great to see some panoramic viewer use WebGL.
Chrome 9 beta ( Currently examples work better in this implementation )
