XKCD Clock
Free AppAbout XKCD Clock
This app is based on the XKCD Phone comic (http://xkcd.com/1363/). It allows you to set an alternative speed of light and see the effects of time dilation as you approach it. The app clock can be selected to pass time either at the rate time appears to pass in the surroundings to an observer traveling at speed or at the rate time appears to pass for an object at speed to a stationary observer.

While the concept is cool the app needs the user to move to be able to use it. Please add a manual option, so as to be able to enjoy the time dilation effect without having to move around.
