Gregory's Server@futzle Very interesting thread! I can't help but wonder: if they have GPS, they not only sync but can also get coordinates of their location, ignoring height. So assuming resolution of <10meters and assuming buildings are usually >=5meters wide in any direction and have some space between them, wouldn't it be trivial to use the beacon's location as a seed to sync up all the lights of a building but ensure they are different from the beacons of the buildings next to them?

 @jorgeyanesdiez I can't think of a way to do this without the beacon needing to have a copy of a map. Consider in a dense downtown: the corners of different skyscrapers may be across a street only 20 m wide but the buildings themselves fill a 200 m block. Closeness is actually the _opposite_ of what you want. |
@futzle sorry never mind what I just said @weaselx86 had already pointed it out
