NaArMaMo Day 13

[squirmelia]

Another geofence. This time one around the Mars plaque in Otford that plays the sound of the wind on Mars when you go near to the Mars plaque. I'd like to make it so that it plays the sound of the wind faster/slower depending on how windy it is in Otford, but that would require a lot more work and coding of geofences. Maybe eventually.
