autor webu prikresľuje a maže krajiny podľa toho, čo ľudia píšu do komentov: "If there're many comments or questions like that, relevant country will be downsized or deleted. To the contrary, territory of relevant country will be moved or enlarged if there are comments like "more to the right", "larger". At the same time, comments about positional information of any landmark such as a pyramid of Egypt is appreciated."
