title: Google Glass GDK: Progress Indicator?
body: <p>Using the GDK (or in some other way), is there a way to display a progress indicator similar to the one displayed when connecting to a WiFi network on Glass? (the "spinning" lines on the bottom of the display, kind of like at the end of this video: <a href="https://www.youtube.com/watch?v=g3ncmeGaKN0">https://www.youtube.com/watch?v=g3ncmeGaKN0</a>)</p>
  
  <p>Thanks!</p>
