As of this writing, 15 demos are available from the Famo.us site. In all cases, you can play with the demo online and download the project zip file.
Famo.us is currently being beta tested by some 5,000 developers, with rollout to 500 new beta testers each day. The company expects the beta to be fully open by May 19. Meanwhile, the Famo.us Docs (basically formatted comments from the framework) and Guides (actual tutorial material) are available to all. The installation instructions, Demos, and Famo.us University lessons, however, require a login password.
Famo.us promises significantly better performance than standard mobile websites, it's more flexible for UI development than HTML5, and it's easier for developers to use than native code. But as I hope you've seen from this walk-through, the framework currently looks and feels more like an animation or game system than a conventional Web toolkit.
