The title is: we both step and not step in the same River

In this installation for the first step, I was more interested in whether I can use the material or volume to indicate the negative space.
I started this installation by strings. I connected two opposite walls of my studio vertically from the center point by several parallel horizontal strings from one-meter lower than the top of the ceiling to one-meter upper than the bottom of the floor. So, it was possible to move around the space. Two groups of strings crossed each other at the center of the room without touching each other. So, you have a strong sense of a vertical line at the center of the room by connecting the imagined crosses points to each other. The line is compatible with the exact definition of line. It doesn’t have any thickness so it’s not made of volume or material, comes from connection between two dots (which don’t really exist in reality as well).

This work included a documented video of previous work of mine (next one in the documentation), which was a rectangle hole, which I had made into the middle wall in the gallery. The hole was framed from both sides. The title of that work was “untitled or ID photo”. You could see whether other art works or people in the gallery through that. I shot the hole from both sides by a video camera. I projected the first video through strings on a wall of my studio, and the other one on the other side of the same wall exactly at the same place as the first one in my neighbor studio. In this part even the story of the negative space in the wall doesn’t have its material/ volume.
