John Baez TWF week 251 is interesting.

My favorite is this reference to Bob Coecke, ‘Kindergarten Quantum Mechanics’ and the discussion of “picture calculus”.

[Some pictures may worth more than a thousand words?]

“Picture calculus” appears to relate to your thread topic.

From my perspective these are all consistent with some type of mathematical game theory?
