Oh GPS systems seem to be popping up more in Art these days

An old instructor of mine is doing a project that records her activities (commute to work, commute to grocery shops, etc.) on the GPS system and the designs are brought to reality as embroideries
There's a school in Montréal where they've also used GPS systems to create 'spontaneous' or unpredictable designs for weavings... fabric structures
I think it's interesting, this combination of art with new technologies
and also the idea that the outcome will always be a surprise... since you don't know how the 'design' will turn out
