The irregularity, inspired from Japanese aesthetics, is when “there remains something unexplained” that neither perfection nor deliberate or premeditated distortion can achieve (Yanagi, 2013). The experience is beautiful because irregularity brings a moment of uncertainty, of openness, and therefore of freedom and possibilities of changes.
Because it is a beautiful concept.
