This diagram represents represents architecture (the frame) as a topological operator, that is, as an intervention into the topography of the earth. The addition of the mobius strip - the surface with no inside and no outside yet one of each at the same time - pays attention to the inherent paradox of surface. the hard stuff becomes a frame for the soft stuff which rises to the surface becoming a skin, "man-as-skin" of the earth (Michael Serres said). "The modern body becomes would becomes ever more vulnerable as it [peals]peels off its skin: Nietzsche was right to fear disease" (Bernard Cache). Cache thinks architecture is charged with assisting the dermis of the earth to become the epidermis - where it can harden and protect the earth. Perhaps humans will become blobs.
