Sometimes, when looking at rotating three-dimensional silhouettes, they will suddenly appear to change the direction in which they are rotating, even though nothing about the image has changed. This sudden change is because the silhouette lacks any depth cues from shading. Data from an experiment showed that subjects experienced changes more when the image was being processed by their left hemisphere which controls the right side of the visual field.8
