"Global Poetry System is a Southbank Centre project to explore and map the poetry of the world. It’s based on the idea that poetry is all around us, from gravestones to graffiti, from birthday cards to blogs, in the landscape and in our memories. GPS invites you to take a fresh look at where you are and find the poetry that inspires you. Photograph it, video it, audio record it or write it down - tell the world where it is on the map."
the map is worth a look to at
video explains a bit about it.
Global Poetry System
Personally I think its brilliant and one I think you could integrate with other technologies like QR codes .
