The mark consists of a generally circular emblem comprised of a plurality of curved and angular graphical elements. In the center of the emblem the graphical elements are oriented in such a way to suggest the form of a tree having curved branches above, a central vertical trunk, and angular roots below. The roots can also suggest a series of buildings, computer towers, or other modern elements with perpendicular corners. The entire emblem is surrounded by an external border which almost completely forms the outer edge of the circular emblem. At two lateral intervals, the border is broken or incomplete.
