At the university where I used to work they took advantage of their location since a very important avenue ran through the middle of the Campus. We had a pedrestrian bridge for students to cross the streets, we wrapped it up with a giant Banner with real size sudents and from the distance it seemed like students were on the bridge looking down to the street. It was an attention grabber. The last thing we did was to decorate the entire wall of one of the buildings facing the avenue with very atractive design of student life, with 3D cuts. It looks amazing! Too bad we dont have the same freedom ay our Campus now. We dont even have a sign on the building and prospect students get lost all the time. One thing I've been doing is using temporary signs.It's not the same thing but we make an effort.
