#000000 explores the notion of unseeable.
I attempted to visualize the boundary beyond which we cannot see. Human perception can only cover its immediate environment, one object at a time. We cannot see past time, death and our natural abilities to distinguish colors and sounds. Even worse, we can only explore the limits of the unknown within the limits of known, but never beyond that.
Perfect black and perfect circle are both idealized forms, invented by human mind and non-existent outside of our ideas about them. They represent the instances of unknown that are beyond words and images. Placed in the scenes of common and known nature, the obstacle is flat, dominant and opaque. It could be covering or containing something else, but there is no way to find out.
