This came to me in a dream one night. The concept is difficult to convey with 2D graphics; a 3D animation might be more suitable. The upshot is that the outward manifestations of personality are the result of the dialectic between the base desires (common to all humans) and the psychological filters accumulated through life experience (unique to each individual).
Any suggestions for changes to the model, or ideas for how to make it visually more effective?
