'cornered stone' when whimsy is removed from consideration, and more thoughtful theme/titles are worked on, a deeper level shows, one in which a multitude of layers can be peeled back, like the layers of an onion, whether directly or implied... as an example, consider 'cornered stone', perhaps the most conceptually developed of abstract-to-concrete... doing a double take on words, playing with the hidden 'cornerstone', as well as the word, 'cornered', a curved wall of canyon is taken as backdrop, with a canyon city on the curving side... the most obvious of the lot is taking the wildness of the canyon and 'cornering it', that is, taming it - to some extent at least, to put it to civilized use... again, it obviously is a 'pro-human' stance, a recognition that altering a world is NOT the same as destroying it, only changing it - and the implied recognition that change is natural... the implied 'cornerstone' alluded to in the theme/title, also implies that this is an opening gambit to a human structured changing, instead of the haphazard nature changing that is a consequence of the dynamics of the world of reality...
