In #Paris, you can learn or review major equations on the wall while waiting for the #subway... Is it the new street art ? https://octodon.social/media/DN-UL4j4c2HBFMI6fFc
@PiSquare Sure ! :-) But they're so long that they start in the subway and you have to follow them down to the catacombs under Paris...
And I've just seen today a musical score of Mozart in the walls of #Marseille 's subway (but didn't had time to take a photo, sorry...) I do like when such "eternal" pieces of culture are shown on places of everyday's life...
@xtof54 are there also the proofs printed?
