Need optics help: Figuring out ray diagram for "illusion bowl"

<p><a href="http://www.physics.brown.edu/physics/demopages/Demo/optics/demo/6a2035.htm%5B/url%5D"&gt;http://www.physics.brown.edu/physics/demopages/Demo/optics/demo/6a2035.htm&lt;/a&gt;&lt;/p>

<p>"the image is produced by the double reflection from two concave mirrors"</p>

<p>so we have two concave mirror put together to form a disc type apparatus with an opening on the top where the image appears of the object at the bottom.</p>

<p>Anyone think they could help me make a ray diagram of this? It's kind of confusing</p>
