Nomadic culture

I want to focus on the nomadic way of life. I have been looking at traditional nomadic culture like native americans and how they moved around hunting but felt although it is interesting i want to focus on how nomadic culture works in the western world now and what it means to be a nomad. I also want to look how nomadic structure has become a art form more than a necessity in todays modern world. I have a interest in temporary space and structure so i feel that this is a natural path for me to wonder along. Also these are the things i will be researching for my dissertation.
