Here are a few settings that I've gotten to work with the new Orbit slider that is part of Zurb's Foundation 4.

    })
;

.orbit-container {
  .orbit-prev, .orbit-next {
    display:none; // hide the previous and next buttons
  }

  .orbit-timer {
    background-color:pink; /*! no homo */ // change the background of the timer
    
    .orbit-progress {
      background-color:purple; // change the color of the overlayed progress bar
    }
  }  
  
  .orbit-slide-number {
    // move the slide numbers to the bottom right corner.
    top:inherit;
    left:inherit;
    bottom:13px;
    right:13px;
  }
}
