That's a great observation on the wallwart - I know how much rearranging I have to do on my powerbars to configure all the different shapes.

There seem to be apps designed to let you create an Airplay Receiver out of just about anything (https://play.google.com/store/apps/details?id=com.bubblesoft.android.airbubble&hl=en), and other apps designed to let you use an Android device to run them (eg http://evolver.fm/appdb/app/honey-player)
