This chair is part of a series called Thin Black Lines, the series includes a chair and clothes rack intended to apear as sketches in the air or calligraphy symbols. Slight black lines like the traces of sketches drawn in the air made transparent surfaces and volumes appear, which we assigned practical functions. The outlines remained after simplifying paintings of plants and animals. They are condensed expressions of meaning, similar to Japanese calligraphy. The designs gently break the relationship of before and behind, and traverse at times the space between two and three dimensions. Multi-faceted and constantly morphing, they move alternately between the becoming and collapse of form.
