Art student Sara Watson recently demonstrated the power of paint by painting a car to disappear into the surrounding parking lot. See it at BBC:
Much of what we see is paint, of course, or other things equally insubstantial: veneer, chrome, ink, paper, summer clothes — a visual surface made just heavy enough to hold together. For that matter, we may spend hours a day looking at things that are insubstantial and ephemeral, the fleeting images of film, television, computer, stage. It is not things’ physical weight that makes them real to us, but their spiritual weight.
