Leaving Termini in Rome, in 3D. Uses the parallel viewing technique en.wikipedia.org/wiki/Stereoscopy Recorded on a single camera at 25 fps, with the right side delayed by one frame. Assuming the train was going 40 k/h, each frame is about 44 cm apart -- a bit more than the width of human eyes, but not significant enough to destroy the effect.

You can do this for yourself so long as you separate the left/right with a delay that creates about the width between the human eyes between perspectives. As a rule of thumb, at 30 fps, 1 frame is approximately the distance in centimeters of your speed in kilometers/hour (10 km/h / 30 fps = 9.2 cm).
