Tools other than words as words

Tools may well enter a syntagmatic relation with other tools, such as within the network of objects of a collection. I am also thinking of the museum and the art exhibition as well (a paradigmatic relation). Eventually, all who can abbreviate Duchamp's urinary operate with it pretty much as they operate with a word.

And what is cinematography but a rendition and reflection of objects, including landscapes, "nature", as well as signs and symbols. I am thinking on the syntagmatic of Einsenstein and Kuleshov before filming carried any sound at all. You see the face of a man and a dead child and you conclude that the mad is sad. You see the same face of a man
and then you see a girl in a "lascivious" position, and you conclude, well... something else. When were faces, dead children, spoons, etc. internalised? They were internalised before or after the film? Before or after the two film "shots" required to have a syntagma?

The Kuleshov experiment

Yet the public escaping from the train arriving at the railway station, theme of the film made by the Lumière brothers, had internalised the train as what? Why people no longer escape from cinemas when they see a train or a bullet coming towards them?
