Well in my last semester of my Bachelors our professor told us to go around the site and take a single photo and make project out of it. Granted there was very little structure but it proved to be more or less like a thesis. The projects that came out were quite provocative. In the end a thesis is just proving what has been long established to be wrong. For example my professor once said in his own words “Your program can be anything as long as you challenge convention. It can be a prison so as long as you solve the major problems. First thing I would try to fix are dudes trying to butt fuck each other.”
