I just thought I'd share something I found.
This photo was taken in one of the buildings of the university I'm currently a student of. It was used by the chemistry students before (and a lot of their stuff is still there). This door leads to one of their laboratories.
This picture is definetly something you're not expecting to see there. I do wonder who made it and what it means. ("Beware of foxes"? "The chemicals inside might change you into a fox"?)
