I visited Boston with work, and while I was there I took a look around MIT and Harvard. I picked this up at the MIT Museum (which is well worth visiting!). It is a book about MIT "hacks", which are generally clever re-decorations of part of the campus. The hacks are a combination of demonstrating engineering aptitude, subversion, and effectively student ownership of the campus environment. They're unofficial creativity, and I find it fascinating how books like this show the university is well in control of its own mythos. Oh, and the hacks are quite fun! A nice souvenir.
