For something that would be a little more interesting, you could use the accelerometers for this, as well. I don't know how accurate they are, but they would certainly work even indoors for determining distance moved. The problem, here would be getting a high enough and accurate enough time strobing in order to come up with a reasonably accurate distance. This would be closer to "extremely complex" than the GPS, but still fairly trivial from a top-down view.
