Laser spots

    Why is it that when looking at a laser (not directly, but from an angle) it is possible to see a pattern of spots which flicker around randomly?

    In the site above it says: "The speckle interference pattern forms on your retinas regardless of where your eyes are actually focused". How can this be? Is this a cause of low divergence?
