Project "Bottom" is a laconic statement about variability and constancy. In the sandbox presented in the center of the hall there is a "secret" - a video where virtual sand runs non-stop into a funnel.At the same time, the sandbox remains filled and static. The project is complemented by "secrets" with photographs where only those fragments are visible under the sand in which the image is illuminated or distorted. Playing with virtual and real material artist focuses on the conventions of our knowledge of what time is. It also makes you remember what is considered to be objective and measurable - about speed and about the transformation of matter.
