Here's a suggestion on that video, xmodSpeed. To add validity to the display of speed, make a video of a run in between two points of a known distance(i.e. across tennis court, basketball court, etc.) and have the camera in clear view of both points so that one could use a stopwatch and undoubtedly know where to start and stop the time. The math can be done to find out your land speed, AND it's a great reference for online drag racing competitions! Just a thought. Sound fun?
