Full or Empty

I try to create negative volume by using the achromatic lines, represent the space by division and proportion, and make the shape and contour. The strings give volume, movement, gravity and density. I am curious to imagine the abstract form in the empty space and actually do it in the space. I create a mass of strings which has the volume of a cube. The strings create numerous faces, ans they make optical illusion. I try to create a live op-art installation in the space with strings and build my imagination in the space.
