Static images on a wall that appear animated as the train moves.
@marcioaleks That's clever but surely it only works on cameras? with the naked eye (without a shutter) wouldn't you just see a series of blurs?
@jackeric @marcioaleks works just like the early https://en.m.wikipedia.org/wiki/Zoetrope see the section subway zoetropes for other examples
Zoetrope - Wikipedia

@jackeric @marcioaleks

Seen similar in tunnels - stroboscope timed to match train speed. Which does work with naked eye.

@marcioaleks better frame rate than my TV
@marcioaleks where is this? It looks amazing!
@marcioaleks genius! would love to know where this is.
@marcioaleks clever, works in the same way that a zoetrope works.

@robchapman @marcioaleks the train moves, accelerates ; the camera takes pictures every nth second. This last step produces a stroboscopic effect our eyes (and brain) see as a continuous movement.
I mean this illusion is not visible with naked eyes, without stroboscopic effect. Daylight, you need a camera, or to blink your eyes; nightly, the artificial 50Hz light might make the magic happen.

PS: frankly, I keep being a bit skeptical about this movie. More than ever before, illusion can hide everywhere in the digital world. The fascinating part is that it could anyway help us understand the reality behind our senses.

@7tonin @marcioaleks it's known as illusory Motion, where any optical illusion appears to make static images move. The Stroboscopic effect is the most common illusory Motion. However it is not a new thing that requires a camera, as the effect was first described by Aristotle between 384 - 322 BC
It is like a giant zoetrope, however I do think in this instance the camera plays its part in what we as viewers see here - but, the only way to truly know is to go on that train and see for ourselves.
@robchapman @marcioaleks Hope this place is not out of our reality.
@marcioaleks please tell me this is not AI generated, and also please tell me where can I take this train
@marcioaleks Cleverly done! I wonder how many images there are in total. Can you tell us where this is, please?
@marcioaleks
Where is this movie picked from?
Any credits?
@marcioaleks There’s something like this in New York City in the subway going between Brooklyn and Manhattan on the D train. It’s slits in a tunnel wall with the “frames” behind them. Will try to film it soon-ish.
@marcioaleks Ga! Almost my entire life I've wondered why subway tunnels didn't use this obvious tool, this low hanging fruit.
@marcioaleks
Nice!
How long is that mural, then...?
Must stretch...100s of meters?
