    renderer.material.color = Color.red;
}

function OnMouseExit()
{
    //Change color
    renderer.material.color = Color.white;
}

function OnMouseUp
{
     //are we dealing with a quit button? if is quit button = true
     if( IsQuitButton )
     }
     //if its true quit
     Application.Quit();
