Following our initial brainstorming session (I can say brainstorming right..?) we had concocted all sorts of ideas as to what we could do collaboratively. One idea that came from the cooking pot was to create positive and friendly postcards that we could leave in places for people to find. Ideas included popular books in libraries, phone boxes (not that many people use them these days) bus stops and various other places where the general public congregate.
There is a similar concept in place called postsecret, where people create or manipulate postcards to include messages on them and then mail them on to other people
