The purpose of any representative design (like a portfolio or a diagram) is not to become an illustration itself. Still, while showing the quality and function of the design, it aims to locate itself in the background silently and honestly. When the design requires more from its representation tool, that tool can subtly become more than helping the primary purpose. A precisely organized hierarchy between "how the story is told" and "how the design is created" could cause complications for the observer. But sometimes, the do-er has to know how to enjoy the expression process. This balance comes from the value of the approach firstly, then projects it towards the outcome.
The observer doesn't need to know the enjoyment of the creator, but maybe, sometimes -as you did now- could stumble upon the background by coincidence or accident.
