This is a logo concept for a social network website called ?????? (Kloobok), which means "clew" in Russian. As you can see, letter "k" is hidden in the center.
I particularly like the bright colours, it's immediately recognisable.
To brand a country is a potentially daunting task! This logo for Romanian tourism is an excellent attempt at capturing the essence of a country.
I love the vague use of the country outline and vibrancy achieved through the dramatic use of colour!
