Reality is where the dirt lies

Was it Laurie Anderson who said that VR would never look real until they learned how to put some dirt in it? Singapore's airport, the Changi Airtropolis, seemed to possess no more resolution than some early VPL world. There was no dirt whatsoever; no muss, no furred fractal edge to things. Outside, the organic, florid as ever in the tropics, had been gardened into brilliant green, and all-too-perfect examples of itself. Only the clouds were feathered with chaos - weird columnar structures towering above the Strait of China.
