This is a game for our time. I play it on New York and Boston subways, but you can play it anywhere everybody in a crowd is staring at their personal rectangle.

I call it Rectangle Bingo.

Here’s how you play. At the moment when everyone is staring down at their personal rectangle, you shoot a pano of the whole scene. Nobody will see you because they’re not present: they’re absorbed in rectangular worlds outside their present space/time.

Then you post your pano somewhere search engines will find it, and hashtag it #RectangularBingo.

Then, together, we’ll think up some way to recognize winners.

Game?
