That is pretty neat. It makes the video look like it was taken off a first person shooter or something. Its got that synthetic kind of smoothness to it. Digital Image Processing knows no bounds! You can even use it to perform vibration measurement or check out small displacements. I have seen a manufacturing tool where a camera watches cars on the assembly line and when a car door is slammed it is able to show, with overlaid vectors, how far and in what direction everything moved. It essentially can show the pressure causing the windows to bulge when you slam a car door.

I think the technique is called Eurlerian magnification. Its the same kind of thing that can look at your face and detect the imperceptible changes in facial colour everytime your heart beats. It can work out HR just by looking at your face.
