Facebook Home, the latest creation of Facebook for AndroidOS had the graphic part developed using Apple Quartz Composer, a free component available together with Apple's Xcode. The designers of the Facebook company seek to offer extended functionality to Android applications with the help of this software, and Facebook Home is the best example so far. Although it seems strange, the use of such software to develop an interface dedicated to an Android application is not difficult to understand, Apple offers its developers extremely complex and well thought out programs.
It's no secret that many of us on the Facebook Design team are avid users of QuartzComposer, a visual prototyping tool that lets you create hi-fidelity demos that look and feel like exactly what you want the end product to be. We've given a few talks on QC in the past, and its presence at Facebook (introduced by Mike Matas a few years back) has changed the way we design. Not only does QC make working with engineers much easier, it's also incredibly effective at telling the story of a design.
information coming from Julie Zhuo, product design director at Facebook, and probably based on them many will change their way of working in terms of developing applications for Android OS.
