RFID

I really like the idea of using RFID for our project to implement the locations.  This would solve the problem of not knowing where the mouse is if the user picks it up.  This would also add a wire if we put the RFID scanner inside the sheep, and the tags on the 3D map.  On the other hand, the RFID tag could be embedded in the mouse and the scanner could be on the map.  Then when the user picked up the mouse, he/she could be  instructed to put it back on the RFID scanner start space.  This is just a random idea influenced by working with RFID tags in lab yesterday.
