A new application for Macs leverages the AirPlay technology found in the iPhone 4S and iPad 2 to mirror the screens of those devices onto a Mac running Snow Leopard or higher. Called Reflection, the app can simply show the screen or put a "device shell" around the screen to simulate the look of an iOS device and its contents. The program utilizes the AirPlay abilities to wirelessly stream visual and audio information from the device to the Mac.
