It may be trite to say so, but I would cite Nature herself as my strongest single influence. The antipodean epicenters of both loveliness and horror are to be seen there, and there is no manner of artifice which can pose a serious challenge to Nature's primacy in either extreme. Stopping to smell the roses is literal for me, and I try not to miss a rainbow ... but I am just as drawn in by parasites, and natural processes of decay, and medical imaging showing the inner workings of my physical body. As Nature is one of those truly universally known forces, I see no need to provide any links demonstrating what Nature looks like. However, I would feel out of line if I did not give her first billing here.
