Viper SmartStart -- free app uses augmented reality to help you find your car

The main purpose of this free app is to work with a gizmo attached to your car so that you can start it remotely with your iPhone. But they've recently added some features that make it useful for you even if you don't want to invest a couple hundred on the remote start hardware. Viper SmartStart now includes SmartPark, which uses GPS to help you find where your car is parked. And the SnakeEyes feature of SmartPark lets you hold up your phone to see a live image, and guides you to your car using augmented reality. Plus, if you download the app and give your email address in the Get More Information, you'll be entered in a drawing to win one of 10 iPads.
