z² - w²

• As with all of these, note that the link never changes during the rotation. 
• This is the most basic example of the Milnor Fibration
• The link is a (2, 2)-torus link, which is just two interlocking circles.
• The genus of the "double fiber + link"  is (2-1)(2-1) = 1, which means it is topologically a torus.
• This example has close connections to the Hopf fibration, which divides the 3-sphere into a family of interlocking circles.
