Abstract: A series of interrelated solid, geometric shapes having informational - processing applications. Each solid, geometric shape may be assigned a specific meaning; additionally, any one solid, geometric shape may be assigned several specific meanings by changes of color, braille, scoring, texture, and/or tone (sound). Means for connecting different solid, geometric shapes are provided and are called connectors, which may or may not be assigned specific meanings or several meanings by changing the solid, geometric shape, color, braille, scoring, texture, and/or tone (sound). The series of interrelated solid, geometric shapes may be used for (1) physiology--fine motor coordination, visual or auditory/tactile perception, and joint hemispherical stimulation of the cerebral cortex and (2) communication--language, history, art, computer programming, computer processing (grammatical and parallel), and abstract thinking.
