GravityControls
A simple application for controlling your device's music stream with the built-in accelerometer. Simply flip over your device to mute your music. Flip the device back upright to resume.
Great for when you're listening to music at your desk and someone stops over to ask you a quick question. No need to fumble with a lock screen or unplug your headphones.
Originally I wanted this app to actually pause the current track, but since there is no standard way to interact with the variety of media player applications, this has proved to be extremely difficult.
