Check out this impressive final major project by Stefen Clark on the subject of prisons and the prison system. Inspired by real prison visits as part of his research, Stefen managed to see contraband weapons first hand, as well as discovering the techniques used by inmates to smuggle them around the prison.
This research is evident in the project, which features many hiding places and hidden messages within. It even includes a book that’s smuggled inside a book that’s smuggled inside another book that’s presented inside a safe!
