This is a social capital friendly street art that is appearing around New York City. I’m interested in learning more about whether it is working. The artistic effort is called “Living Exercises”; not sure who the artist is.
One assumes there is a lot of self-selection going on here — the misanthropes are unlikely to sign up, but maybe this a useful social capital nudge for those of us interested in making new acquaintances.
