There are three views to the game:

• Public display in Times Square
• Handsets
• Web site

Correspondingly there are three groups of participants in the game, with decreasing involvement:

• Students in Manhattan, using both the Web interface and the custom client software in the handset
• Web site visitors who affect the game directly in real-time via the Web interface
• Audience in front of the display, who may visit the web site or follow the game passively

The game is based on the following techniques:

• GSM Cell ID -based locationing in Manhattan
• Live photos taken by the players with their camera phones
• Asynchronous Web interface
• Real-time data visualization on a large public display
