The Museum of Illusions in Zadar possesses a kaleidoscope, the illusion of the chair, optical illusions, holograms, the illusion of the dented face, the table of clones, tricky rings, head on the table, gramophones, the whole with no end, room of mirrors and other visual illusions.
In Zadar's Museum of Illusions, nothing is as it seems to be. In the crooked room it defies gravity, while in the room of mirrors you are being narrowed and widened. Holograms, optical illusions, kaleidoscope, dented faces, table of clones and other illusions, are part of that tricky word. Climbing the ceiling is part of the museum's attractions.
