Paint it Google
Zoom to see brush strokes at Google Art Project. But wait... can you see the brushstrokes in Roy Lichtenstein's Brush Stroke (1965)? I once ran into Linda Sampson in Times Square and asked her what she had been doing. She said, "Oh, I have a job painting Roy Lichtenstein's dots."
Below Google shows how they did it. The videos in this series look superb in HD and full screen.
