Asemic writing is writing that carries no semantic value.
Cooking maifun rice noodles one night I noticed a similarity between the thin brittle noodles and marks made by a pen. I took some noodle shards into the backroom and photographed them on a scrap of black paper. Then, as if the photos were negatives, I 'developed' them in photoshop. The result: 'asemic maifun'.
