I've said before that I felt like AirPlay Mirroring was one of the most underrated features of iOS 5. The ability to wirelessly stream content from the device to a TV seemed like an open invitation for iOS developers to create console-esque games.
We've seen a couple of big name titles take advantage of this, but perhaps none of them showcases the feature's potential better than Cerebral Gardens' recently-released Party Doodles...
