I realize now that this and the following picture of my wall might make me look like something of a psychopath. I never thought of that way at the time. I imagined it a bit of a collage for which I made use of the wall simply for lack of a cork board or other bulletin board type of object. I do not now nor have I ever again had a wall that looks like this, but I can't say that I have not contemplated doing something like this again. It seems like a suitable way to get ideas in front of me.
