iPad and iPhone communication

[Electaguitar]

Are there any apps that allow the iphone being used to control the iPad? I know theres a game called pad racer, but its stale and repetitive. Any other games or apps like this?

Scrabble. But you need an iPhone or iPod Touch for every player.

Chopper 2 can be controlled by the iPhone/iPod Touch and displayed on the iPad
