You could totally do this in your dorm room with contact paper or removable wall graphics from www.ltlprints.com/ Don't worry - the LTL Prints don't peel paint and you can stick/unstick as much as you want.
From pinner: I have flashlights in every room. I also wrote the name of the room (ex. Master Bedroom, Kitchen, etc.) on each flashlight with permanent marker. That way, if someone picks it up and walks into another room, they know which room it belongs in! I like this idea to put one at the breaker panel!
