I think I saw a news program on Game Theory. It was very interesting. There were various segments highlighting different parts of game theory (I remember one segment had the employees of two different companies competing to lose weight- but only one company had weekly meetings to try and raise group morale... something like that).
My favorite segment was one in which they approached groups of people (generally 2-3 in a team) in Washington DC to enlist them in a game. The object of the game was to find the other groups that were randomly approached and accept the challenge. They would have to find these people they didn't know anything about- except that these people were also looking for them- within the day- I think they were informed late in the morning and the deadline was about 5-6pm.
Apparently the news program had done a program on game theory before- the same game, but run in New York. Predictably (to me anyway), the groups were able to find each other at the top of the Empire State Building. (Even though New York City is so populous- the idea of meeting someone at the top of the Empire State Building has fairly seeped into people's consciousness from movies like An Affair to Remember and Sleepless in Seattle.)
However, it proved that it was actually more difficult for the groups to find each other in Washington DC (even though it is less populous and the landmarks are closer together). Perhaps a case of too many landmarks, there was lots of running around to various places (White House, Lincoln Monument, etc.)- with pretty much no groups being willing to stay in one place. Spending a lot of time in traffic between the locations reduced their ability to find each other. But they had plenty of cool strategies- like carrying around posters and one group ran into Kinkos to make flyers "ARE YOU LOOKING FOR US?" that set a meet time and place. It was a long time ago, but I believe one or two groups gave up, but three groups did meet up finally finally at the Washington Monument. (Which I predicted, yay! Cause it's tall and visible and has a fairly small "meeting zone".)
