How Heavy is a cloud?, art work which entitles the exhbition is a video and photographic installation that documents my journey from Kraków to Oświęcim (Auschwitz) in thick fog. Disturbingly familiar is a sound piece with 16 postcards, in the form of a travel-diary from my trips across Poland. Ask the stones are stamps made of iron with questions which evoke the ambivatent feelings of my journey as well as notions of identity and memory.
