What is a 'Psycho Scribble'?

They are the little drawings I do as I go about my day to day activities. The best thing about them is that they are completely spontaneous. There is never a thought to what they will become ... I'm much to preoccupied with other things to give much thought to what I'm 'scribbling'. They simply become what they will be. They express my moods as I draw them. These are the best examples of my subconscious thoughts and feelings being externalized onto paper.
