The book consists of photographs of the walking yard and prison cell door spyholes in former political prisons in Eastern Europe (Estonia, Latvia, Lithuania, Ukraine, Poland, Germany). The same places were used for similar purposes by different oppressive systems.

The actual work call into question the relation between what we see and what we perceive in advance of the act of recognition. These photographs emphasize the borders not only of human perception, but the border where the consequences of human action meet reason.
