The Motion Blur filter lets you add "speed lines" to your artwork. This can be used to simulate motion. Each speed line is created by modifying an existing anchor point on your selected shape.
The Angle slider lets you decide which direction the speed lines should tilt in. As you move the slider, you'll notice feedback in the preview image that will help you position the lines.
The Distance slider lets you set the maximum length of any speed line (remember, they will vary from 0 to this length). The units are whatever units your document's ruler is currently set to.
The Line Width slider lets you determine how fat or thin the speed lines can be. This is a percentage based upon the length of the rockers for any anchor point. Keep this percentage small for best effect.
