I have chosen to look at this image, not because of the artist, but the way in which it exhibits focal plane distortion, a related topic to slit scan photography. Because the shutter of the camera moved at a high speed, it was beginning to close before it was fully open, as it moved across the image the car moved past the camera, causing it to lean, while it was panned to follow the car (albeit more slowly than the car was moving) causing the crowd to lean in the opposite direction. Notice that the wheels are not recorded as circular, but ovals, due to them moving as the focal plane moves upwards.
