Adam Magyar shoots 50 FPS video of the people standing on the platform from the train as it makes its way into the station. He then slows it down, so that just a fraction of a second of real time becomes seconds. The tracking effect of the moving train is real, but the people seem frozen, stilled in time. The effect is ghostly and voyeuristic. See for yourself.

Regarding the vimeo (not the books). One word: Pompeii. They know not what awaits them.
