Act of unseen (2018), is a performance piece made in Etretat, Normandy 2018. Where Siagian asks himself the question: "how to describe the lining of air when she moves by the wind?".
He went on a trip to visit the sea surface underneath the cliff of Etretat. His work intends to capture the image of air merging and where the movement of the air is controlled by the wind. Siagian uses 2x3,5m red cloth fabric that he opens widely with his two hands above his head and with his two feet, he stands straight and close to each other. Almost like a pillar as a gesture of surrender. The fabric is waving in a different direction according to the wind taking control.

Siagian motivation is to capture every sequence, so he can translate every shot of one second as a memory to the unlimited time of the image. He analyzed the video record afterward and selected a print screen of each sequence per second.  Every pose of the cloth is very unique to each layer of the framing. Siagian fascination was the environment and its sensibility. Every time he closes his eyes he wonders how the air is and how it moves around him.
With this work, he finds a way how he can translate his imagination projected onto a piece of fabric.
