Assemblage collection is an experiment of effects of two different metal properties when they are together. Unique color and reflexibility of each metal make visual contrast which is never seen before. Stiffness of stainless steel performs as a perchable objet perfectly. Without additional part, I can make self-supporting structure with laser cut. So, people can focus on natural charm of material. Assemblage collection creates various images depending on viewing angles by blurred boundaries between the objets, resulting in novel spatial effects.
