Philip K. Dick said this quote
“ He could see the tall, peeling yellow building at the periphery of his range of vision. But something about it struck him as strange. A shimmer, an unsteadiness, as if the building faded forward into stability and then retreated into insubstantial uncertainty. An oscillation, each phase lasting a few seconds and then blurring off into its opposite, a fairly regular variability as if an organic pulsation underlay the structure. As if, he thought, it's alive. ”
