Hot targets and RFID frisbees
Two teams both have a frisbee with a built-in RFID chip. They play in a field with three goals featuring RFID readers. The goals randomly light up (become 'hot'). When a goal is 'hot', it becomes a target. Whichever team places their frisbee on the target first, scores a point.
Developed at the Mediamatic Social RFID Hacker Camp 2009. Location: the square next to the PICNIC Club.
This and 10 other Social RFID projects are part of 'Play with your Tag' at PICNIC09.
