What?

Players create and perform GPS-enabled tasks. A task is a response to a particular site, inspired by its design, use, rituals, acoustics, history, etc. A description of the task is uploaded in audio, text, and/or image. As the file is geo-referenced it can only be unlocked when someone else passes these coordinates. The results of the (collectively) performed tasks are uploaded in realtime. Points can be assigned to performed tasks. The player with the highest score wins.

How?

The prerequisites for creating and performing tasks is that you are outside and carry a mobile phone with 3G. You can participate in this game by creating tasks, performing tasks, and assigning points.
