From the ‘elegant fun’ department: these kinetic sculptures by David C. Roy remind me simultaneously of favorite screen savers, animated crop circles and perhaps a few other moving mandala metaphors for cyclic interactions and relationships with curved arcs, circular and Yin/Yang archetypes; some lovely examples of moving geometry suitable for adorning one’s walls. His site has some engaging videos and other fun stuff on his blog.
More geometric art from artist Karen Carty in northern California … golden rectangles and spirals on large canvases
… and another gossamer golden ratio design of threadlike elements (found via a quick google search :-)
