This thing keeps getting hyped but all I've seen so far is this periodic table demo which doesn't really do very much - just move some images around with css 3d transforms. I mean, it looks nice - but it's not very functional. Have there been any demos of useful, interactive, data driven apps or interfaces? It also rubs me the wrong way that their private beta is basically bringing people into their office to work for them for free so they can showcase the demos they come up with.
