Awesome stuff ;]
The frame rate is good for me on my browser (firefox)
Will this fare well on mobile?
Quoted from the wiki:
Nokia N900 - WebGL is available in the stock microB browser from the PR1.2 firmware update onwards.
BlackBerry PlayBook - WebGL is available via WebWorks and browser in PlayBook OS 2.0
Firefox for mobile - WebGL is available for Android devices in unstable builds since early 2011.
The Sony Ericsson Xperia range of Android smartphones have had WebGL capabilities following a firmware upgrade.
Opera Mobile 12 final supports WebGL (on Android only)."
Hopefully chrome and safari will support it soon ;]
