The first thing I did when I saw Famo.us last year was rip into the code. With a little persistence, you can pretty easily use the code without waiting for their release.
I prettified the code myself too, but it's really unreadable. Have you extracted the parts into a nice library? Mind sharing your efforts?
Honestly, without going into the source code, I was like, this is matrix transformation, this is matrix transformation.. then I saw matrix3d and I was like yeaah!
I believe that no software can excel without a good mathematical foundation. What I see coming is that this approach will be extended by P2P Load-Balancing. Similar to what Bitcoin Hackers [1] were doing and still do [1].
The example shown on famo.us is identical to MrDoob's Three.js example that uses CSS3:

Edit: looks like it's the other way around -- according to MrDoob's G+ post from last year, he based his Three.js CSS3 example directly on the design created by famo.us: https://plus.google.com/113862800338869870683/posts/QcFk5HrW...
