[NTG-context] vertical interactionbar?

I am trying to make a presentation with a progress bar. I want it along the right edge of the screen. I remember seeing something like that but cannot find it now, and all the alternatives for interactionbar seem to require a horizontal one. How can I make a vertical progress bar?
