i'm a senior principal with the architecture firm of polycarp pally, and the art program -- pelly clark pelly, and the program has been organized similarly to the art program, in the sense that it is being done in phases, so we are reporting to you today on the conclusion of the concept phase of four or five pieces, and i must say that a great deal of work has been done. i think, where advanced even beyond the concept phase. let me frame how one might view this kind of program. first of all, although it is a five-artist program, which is relatively small, this is a very large building and a very large project, so each piece needed to be of the size and scope and scale appropriate to this very large building, so i think you are going to be seeing each individual artist dealing very successfully with just the sheer size of the building, the number of people who will be experiencing the art, and, of course, the importance of this building in the city of san francisco. second, there is a great variety of art. we have taken this opportunity to kind of expand the notion of art, 8 you will, well bey
