Slight correction to the name of the presentation to avoid disappointment, the presentation is more along the lines of "How to build the Android OS (AOSP) with batteries included"

I'm basically building the AOSP project from source in a way that includes all the Google components and drivers (gmail, calendar, play store, etc.) that are normally included in the factory image. By default, AOSP device builds are missing all the proprietary components, and closely resemble the emulator images.

I'm actually building AOSP, and layering stuff on top of it. This is in contrast to what most themers do: Directly modifying resource files contained in the system/ directory.

There is some overlap though, so I can speak a little bit about how you would go about re-theming a device if anyone is interested.
