Playground and demos broken or confusing
From 3 comments
The playground seems broken (stuck on "Let's play...")
oe on HNShould the 3D demo work on IE11? It started fine but then broke, on desktop and wp8.1.
leo_mck on HNI wonder if other people also see the jitters in this demo when the box is returning to left? http://cdpn.io/pLAxF (click the red box)

Link to a live demo
From 2 comments
Can I just get a link to the demo please? There's no reason I should have to watch a youtube video in order to see a javascript demo.

Nice, how does this compare with Greensock's performance? Is it better, or about the same?
