Stellarium is an amazing 3D planetarium software that was just ported to the PlayBook. The app is based on the open source Stellarium Linux/Windows project and does a great job of making it all touch friendly. I am not sure if the developer is associated with the Stellarium project but either way I have to say I am impressed with how this app packs the whole view of the sky into your PlayBook.
