My name is Kevin Greer, and I lead the FOAM project at Google. Answers in-lined below:
> a mature app written this way
I've added links a number links to FOAM apps for you at the bottom of http://foamdev.com.
We have a number of mature apps.
QuickBug, which is a codesite issue tracker, is about two years old.
MBug is a mobile version, is about a year old.
The ChromeOS calculator was written last summer as a demo but went into production just recently.
There's also a rough but working GMail client.
The Chrome App Builder is also in production, but, unlike the other apps, isn't open-sourced.
We also have a couple very large internal Google apps that I can't talk about.

FOAM was started in 2011, and generated its first production code, in C++ and JS for Chrome, in early 2012.
The first part of the slides is on using the apps and the second part has a bit about how we developed it (but without speaker notes, it may not make a lot of sense).

Here's one: https://docs.google.com/presentation/d/139TUw8tLtqRzFSHGoLTQ...
I have several others as well, but I would need to scrub them before making them public.
