A blink takes 100-150ms. For the 100m dash, Usain Bolt takes 41 steps in 9.58s, so 231ms per step. Either that kid is really hauling ass or the blinks are people completely shutting their eyes at the disturbance of the train's arrival, which is plausible. I don't spot anybody blinking in the background, unfortunately. I guess the easiest way to get timing would be to measure the distance between the pillars. Odd appearance made for fun little puzzle to play with for a minute.
This article briefly mentions it at the end, but I didn't understand it until I saw one of his videos explaining it:

I'm guessing this would be fairly trivial reproduce with a regular digital camera by taking a normal video, and convert it into a "scan photograph" with an ffmpeg plugin or something like that.
I wonder if something like this already exists?
