Mathew Cusick makes collages with maps. There's a whole series of them on his website but I'm including this one because I imagine that it would look grand in a big loft space. Plus I think my brother might like it.
I just discovered this recently- someone called Anatoly Zenkov has made a computer programme that maps your computer mouse movements. And this can be the result. The black spots are where the mouse has been resting and then the other parts are the mouse tracks. It's great huh?
Jason LeFerra makes wildlife collages with maps. Which I find pretty cool. His Etsy shop is here.
