Inspiration (Inspiration Software Inc.; Mac and Windows, $99) is a visual-thinking tool that helps you clarify and organize your ideas. It displays your ideas and their relationships onscreen, letting you make connections that aren't obvious. From the juxtaposition of ideas, new possibilities emerge.
You begin with an outline view, placing your thoughts in a text mode, but Inspiration's power comes when you switch to the diagram view. This transforms your prose into a concept map, flow chart or other graphic representation. In this mode, you can insert objects or text, move them around and connect them with lines. When you reposition something, Inspiration adjusts the links in both the diagram and the outline so they're always in sync.
