41. An apparatus, comprising: an orthographic projection application arranged to manage a three dimensional orthographic projection of hierarchical information, the orthographic projection application comprising: a hierarchical information component operative to receive hierarchical information representing multiple nodes at different hierarchical levels, and parse the hierarchical information into a tree structure; an orthographic generator component operative to generate a graphical tile for each node, arrange graphical tiles for each hierarchical level into graphical layers, and arrange the graphical layers in a vertical stack; an orthographic presentation component operative to present, in a user interface, a three dimensional orthographic projection of the stack of graphical layers, wherein the stack of graphical layers each has multiple graphical tiles on a display; and an animation component operative to animate a transition between different graphical user interface views for the three dimensional orthographic projection.
