Capstone Part 7: Buttons

I've created buttons for the main menu. Each button has 3 states, a unpressed, a hover, and a pressed version.  The buttons essentially light up and hover every time the mouse hovers over.  I've also created a ring for Saturn that has falloff.  The reason why it has falloff towards the bottom is because of atmospheric perspective.  When you're looking towards the horizon, you're essentially looking through more atmosphere than you would be if you were looking up.
