like a gigantic game of mobile phone powered go against the Baron in lower Manhattan

Crossroads is insanely cool:

"Crossroads is a mobile-phone powered street game. It is designed by area/code for “The Good Life: New Public Spaces for Recreation,” at the Van Alen Institute.

The game is inspired by the traditions of New Orleans Mardis Gras culture, and especially those aspects of the urban experience which have changed in the wake of flood.

Specifically, the game draws from the idea of the second line – the parade of musicians whose route is never determined in advance. Traditionally, the second line moves through the city in a spontaneous and semi-random manner, drawing an unplanned path through disparate neighborhoods and cutting across social, cultural, and economic boundaries. Last year, for the first time, the second line agreed to submit their route to Mardi Gras parade officials prior to the event.

Crossroads does not make such concessions."

I'm particularly captivated from the idea of running from an invisible, computer-controlled entity in realspace....

That England, that was wont to conquer others,
Hath made a shameful conquest of itself.
