Microsoft and Cingular Wireless are co-sponsoring an evening of play to kick off Where 2.0. Pixie Hunt is a mash-up of a Microsoft prototype that creates a mobile, connected scavenger hunt. Combining the app, a Windows Mobile 5.0 smartphone or PocketPC cameraphone, Flickr, and a group text messaging service, tasks are set for teams to accomplish. Each time a photo is snapped recording a completed task, it's automatically uploaded to Flickr and tagged. Photos can be viewed by all teams in real time and teams can "smack talk" via the integrated group SMS service. Because the photos are geotagged, some tasks are created around specific locations for photos be taken and players can see the location of other teams on a Virtual Earth map.

The Pixie Hunt game is for registered Where 2.0 attendees only and space is limited to 60 players. If you want to play, please sign-up on the conference Wiki.
