I was quite surprised at css3 3D transform demos on the webkit.org What is really amazing is that the demos has no update function for frame animation but css definitions for animations.

I just created simple mouse interactive css3 3D transform demo.

NOTE: The demo only support certain computers which has GPU acceleration with webkit browser, safari and chrome.

it's not bad at all because DOM element can receive mouse events, although the performance will be better with HTML5 canvas.
