It's odd, it appears to think that my Linux Chrome isn't Chrome at all. It tells me to upgrade.
Here Chromium 17.0.963.79 doesn't work, but Firefox 12.0 works (actually, I think it's the first time ever a fancy WebGL thing works here).
It's not playable though. I guess my graphic card (or the driver) doesn't have the proper acceleration.
I am using Chrome 18.0.1025.165 (Official Build 132849) on Mac and it works very well.
