"DUNA sétány" is a waterfront project by the river Danube in south Budapest. It's going to be a promenade. The logo is needed to promote the events of the community planning, etc.
It symbolizes the river and the island between Buda and Pest, also contains the "D" and the "S" letters. It's so simple, but it became a bit dynamic with the use of 3D effect.
