Here's a video of my first step towards getting WebGL working within TizMee: http://www.youtube.com/watch?v=HFlSj4RbQSg

I'm using my own version of the QtWebKit libraries (version 2.2) instead of the system libraries (which don't support WebGL), it's currently just running within a simple QT test browser, with integration within TizMee being the next step. I'm also hoping that I'll be able to make use of hardware acceleration for some CSS effects which will make general 2D apps much smoother.
