architecture - a unique building in Sarajevo

This is the building Papagajka, in central Sarajevo (Bosnia and Herzegovina).

There is a psychological thriller being made in Sarajevo, currently in pre-production, that is set in and around this building.- It will be immortalized, which is a wonderful thing for this architectural oddity.
