Visual research on abstraction within graffiti on trains.

There is something very appealing to me within the idea of abstraction. I never truly understood the ways of thinking. Like how some visual stimuli can be so seemingly meaningless but yet beautiful in the way they present themselves to the viewers eye. It intriges me that there are certain systems and guidelines you can follow to make something actively esthetically pleasant to the viewer. And in art there is still a lot of work that thrives on just that aspect which I find very strange and yet romantic.
