Last week, Facebook unveiled Facebook Home; a hybrid of a homescreen replacement, app and operating system for Android phones. I have my opinions about Facebook but I can't help but admire the work they put into the design of this. It acts as a layer between you and your phone. The chat heads feature looks especially intriguing. It looks like the way messaging should be on your phone.
This is only available on Android phones but I hope to see some of the design elements find its way on to other platforms.
