focus the + sign in the middle. You should start to see a green dot that rotates around the circle - this dot is an illusion; then you should see see the purple dots disappear.... but they haven't really gone. It is an after image effect, sometimes called a'negative retinal afterimage' - move your head slightly, and the dots will reappear.
