Visual Writing

The Writer's Toolbox discusses different forms of creative writing in order to get ideas on paper.  This includes mind maps, concept maps, freewriting, brainwriting, and word lists.
Mind maps - starting with one word or object, related words are written around it and then words that are related to those are then written, and so on.  This shows potential connections between seemingly unrelated ideas which helps with the creative process.
Concept maps - again starting with one word, this map shows more of how the brain makes connections between different ideas.  It shows more of conceptual relationships and systems thinking.
Freewriting - a constant flow of thought unfiltered.  This is private writing, so you don't have to worry about it being seen by other, but it shows some hidden ideas by constantly writing what you are thinking.
Brainwriting - much like brainstorming, but is better for those who are quiet.  A basic template is used to generate ideas and is then discussed with the group.
Word lists - start off with a single word, then write down words that are in any way related.  These could be descriptive, metaphoric, or opposites.  Selecting a few words that stand out and further exploring them can greatly expand the design process.
