when I got my first iPhone I discovered that the GPS location is saved in the foto inforamtion. Nowadays not a big discovery but 5 five years ago not even iPhoto showed you that info. So I started to take pictures of my shoes wherever either the location or the motive was interesting.

However I start to think about an exhibition with the photo and the location framed and printed on glass. Maybe a bit too fancy but I like the idea about it.
