2010 has been a great year for iOS apps and the devices that use them. With the introduction of the Retina Display on the iPhone 4 and the generous amount of screen real estate offered by the iPad, Apple mobile product users have become accustomed to beautiful user interfaces that not only look good, but provide them, in most cases, with immediate application gratification. As the year comes to a close, however, one developer has seen fit to bend those gorgeous screens to his will, providing us with an application that doesn't offer instant satisfaction. Instead, Strange Rain--really more a work of art than a game--rewards long-term use while looking good doing it.
