Magic clock knows your location

Straight out of the fiction of Harry Potter is The Magic Clock. Just like in the novel this clock (is it still a clock even thought it doesnt tell time?) shows the current location of family members, from home to the doctor’s office, even to mortal peril (We hear its nice this time of year).
The clock hands are driven by 4 separate servo motors, which are maintained by an Arduino. The location of family members is updated wirelessly via Twitter. We think a script written for each member’s GPS enabled cell phone might be more trustworthy, but it seems to be working fine currently.

Some type of device needs to be in each room that will detect who is in the room. Maybe an RFID pad in each room and a RFID keyring to activate it programed for each person.
