title: A thinking aid.
abstract: Writing a paper is often a process of discovering what you have to say. A small, inexpensive, "three-dimensional" outline of the paper is a help in guiding the process of discovery. New points can be accurately placed as they appear. The outline grows with the paper. The construction of such an outline is described.
