Gravity Monkey GPS Chimes
GPS Chimes – Hooked up to a laptop
My GPS Chimes are wind chimes that are triggered by an individual’s proximity to a given location — networked via GPS, cellphone and the internet. Think of it as mile-wide radius around the wind chimes, where my networked presence and GPS location (via Mologogo) send a virtual breeze to announce my travel home.
Honey, I’m home!
– I know darling, heard you coming from a mile away!
