Sub-Structure

Advanced Mechanics

The Line is the surface expression of a deeper, more complex mechanical foundation. The sub-structure beneath each line provides the true nuance of a design. This knowledge is primarily used in advanced analysis like PHS (Primary Health System) and Rave Psychology.

The layers are:

  • Line (6 variations) - The behavioral expression.
  • Color (6 variations) - The motivation.
  • Tone (6 variations) - The cognitive sense.
  • Base (5 variations) - The foundational element.

Each level is a filter for the one above it. The Tone is the critical link for determining one’s correct dietary regimen (PHS (Primary Health System)) and cognitive architecture.
