The name Pneumatyka directly brings pneumatic systems to mind. I am interested in explanations that follow how pressure, control, and movement connect, instead of beginning with a long list of unfamiliar components. That is the appeal of Pneumatyka pneumatic systems for me. A clear diagram can give a beginner a place to start while still showing that it is a simplified model. I like being able to understand the role of each part and ask what changes when the system behaves differently.
