as for the traveling shapes, and the interior signs and directionals, we've been constructing examples of how they work in google sketchup to make sure the forms make dimensional sense, rather than trying to guess and draw them from one angle. again, these are just examples of how these elements will move, rather than molds that they will all mimic.
an example of a directional hub to tell you which color to follow:
an example of a shape emerging from and re-entering the ground.
an exterior building identifier for vanderslice
an interior wall-mounted directional piece
a bathroom location indicator
