Look, at this point, the only thing that Carly Rae Jepsen's ubiquitous pop hit is good for is experimentation. And, whether you love or hate "Call Me Maybe," you've got to admire what programmer Ryan Challinor—who works at Dance Central and Rock Band developer Harmonix—does to the song.

Taking a heart rate monitor connected to a GPS watch duct-taped to a webcam, Challinor uses his own heartbeat change the speed of the song's playback, via some code of his own creation. A refined version of this concept might be just the thing to make a daily treadmill run a lot more interesting.
