Arrivederci e grazie is an experimental project that explores the receipt as a ready-made object and exploits the physical-chemical characteristics of thermal printing to investigate its material and generative potential. The act of anomalous darkening the paper by using different heat sources had created unexpected figures. Through observation, these figures take on unique meanings and interpretations. When shapes are completely abstract, our minds try to impose a meaningful interpretation even in the face of ambiguity, leading individuals to expand their perception creating an imaginary universe full of figures. This phenomenon is called pareidolia.

The receipt undergoes a transformation from a purely functional item, breaking into unique figures and signs due to consumer practices. The project includes a newspaper and an experimental insert with thermochromic ink on the cover. The first focuses on potential figures from darkening, while the second emphasizes lettering generated similarly, with attention to letters as visual signs. Reflection expands into NFTs through image processing from darkening, attributing value to each original digital token. This process serves as a pretext to turn the receipt from a disposable document into a precious digital art object.
