Ids are visual concepts. Juxtaposed, the elements combine, forning fields, and shine with unique semantic light,–vibrational, spiritual, musical.

As for my last point, that concepts have internal and external aspects, see my post “The Ideographic Familification of Concepts”. It is important to me, tho an elusive and difficult goal, to put ids into families such that similar related ideas have ideograms that are similar or have elements in common.
