1. A Mark Jenkin-esque dummy in the library
This mainly had to do with calling attention to an instance by placing something that isn't usually part of the context of the library, making people stop and look at something unusual and out of place.
2. A small living room in a post office box
This played on the idea of security and our ongoing heightened paranoia, as well as the idea that we live in little boxes that all look the same.
3. Money down the drain
This is a drain on the side of the student union that has money pouring out of it, meant to evoke the idea that money is being wasted. The dollars have a complaint about the school or a school related program written on them, meant to narrow down what needs work so there can be improvement and less tuition money wasted.
