Serendipitous Art: A Wall of Invisible Marks

Recently at the De Young Museum in San Francisco I saw a wall covered with marks—marks made by human hands—around the hand railing on a staircase. They are invisible in most lights, but, at one oblique angle and with the light coming down from above, they appear momentarily...until you move slightly and they become invisible again.
