In readying the iPad 2 version of Two Worlds II: Castle Defense (released on PC, Mac, iPhone, and iPad back in May), TopWare has added a really cool new feature. Using the iPad 2's camera, Castle Defense can track the player's eyes and use that information as part of "3D-ET." This technology allows the player to move their eyes to look around corners in the newly modified game engine. As the viewer looks around, the perspective will shift.
It's a cool idea that has rarely been used in games so far, with the only recent example I can think of being a hidden picture DSiWare game. This technology probably won't be used much in the future because the iPad 2's gyroscope can probably do the effect easier, but I still think it's a neat way of using a camera. You can check out the effect for free by downloading the Lite version of the game, or you can drop money on the full version.
At long last, Republique is out on PC via Steam, GOG.com, and the Humble Store
