Eyes agog. Your pupils dance over Van Gogh’s Starry Night. You stargaze and stare. You want to touch the painting to feel the brush strokes, but you can’t—not because of a grumpy museum guard, but because the painting is a mere image on a reflective screen. Instead of seeing Van Gogh’s signature brush strokes, you confuse your reflection with the pixelated disarray of colors on your computer screen.
