Probably some of you would like to be able to play certain games for iDevices on large screens, such as a TV screen, but still use the iDevice to control the movements in the game. Well, in the video clip presented above, you have a small one demonstration of the Incident application that allows us to play iOS games on a TV screen using an iPad tablet connected with a VGA cable to an Apple TV and an iPhone connected to the iPad tablet to control the actions in the game. I know that it is quite complicated to do this considering that it is about 3 different iDevices, but as an idea I would think it would be great to be able to play certain games on the TV screen.

In order for the whole process to work, it is necessary for the application to actually run on the iPad tablet, to make a physical connection to the Apple TV that displays the images on the screen, plus a wireless connection to the iPhone that acts as a game controller. What do you think, would you spend money on a slightly simpler device that would allow you to do this?
