"DIY" or "Who is the Artist now?" is breaking with the assumption that all NFTs are just one-way works that are supposed to be perceived only. It is a very basic drawing tool that allows anyone do scribble on the blank canvas with a pixel brush and one color only. All the works that the audience create are not saved and only seen by those who draw them and are thus very ephemeral by nature.
It was made on the day when Hic et Nunc enabled artists for the first time to mint works that included code and become interactive. In its plain and rough execution it also is a reverence to the "low effort" approach of the trashart genre of crypto-art.
