 "Filo" might be read as a reference to the greek φίλος (phílos), meaning "dear" or "beloved", but also "a friend" or "a boyfriend", and "Filo" in Greek could be a masculine or neuter dual form, therefore signifying "two dears" or "two boyfriends"; see: "φίλος" in: en.wiktionary.org

 A remark of Łukasz Wójcik.
 Operation Hyacinth (1985–1987) was a large-scale operation by the Polish secret police to gather information on Polish homosexuals and their circle. About 11,000 people were registered, files were opened on them and many persons were arrested (those arrested had special files opened and often had to sign a statement). The operation drove members of the gay community underground. See: "Operation Hyacinth", in: Wikipedia.org

 Karol Radziszewski, Mushroom
(Grzybek), 2019, steel sculpture. Radziszewski's sculpture is a reference to one of popular cruising spots – a public toilet (no longer existent), shaped like a mushroom, standing on Three Crosses Square in Warsaw. The work mimics the style of the famous Polish sculptor Monika Sosnowska (b. 1972), who often addresses issues of socio-political change as manifested in architecture. The crushed and distorted form of the sculpture refers to its demolition.
