I think that this idea is pretty amazing. Benz Thanachart, Thai photographer shouts nonsensical phrases on public transpo, then records the reaction of the other passengers with a photo. He created an entire series of these photos entitled “Smartphone.”
I’m a pretty big fan of art that involves social experiments. There was a period in the late 90’s and early 2000’s that my brother would amuse himself (and others) by feigning a Tourette attack in a crowded space just to see people react. I’m not trying to make light of Tourette Syndrome or anything. But I remember a few instances, particularly on the Vegas strip and in Times Square NY, that my brother pulled this stunt. I wish that I would have had the presence of mind to document the reactions of people.
My additional two cents is that this project would never work on the NYC subway. Maybe one or two ppl would look (if they didn’t have headphones on).
