The idea of simplifying a country's rough shape into such geometrically simple a shape that is a triangle, is brilliant.
Bosnia and Herzegovina's flag uses exactly this concept. And Wines Of Argentina even adds to it by not only using an easily-recognisable triangle as the country's shape, but even elegantly placing parts of a circle around it, thereby placing the country significantly on the globe.
