This is the Mars dial designed by Woody Sullivan at the University of
Washington. He gave a short update on the design at the NASS Conference in
Seattle last year. See
http://www.sundials.org/attachments/article/174/2011%20NASS%20Conference%20Seattle.pdf
for a retrospective on the conference but very little on the dial.
Yes, the sundial is based on a colour comparator and the orientation of the
dial changes when the rover moves. The hour lines lines are added by NASA
back on Earth. The original design is described on Woody's website, more
specifically in the following article. See
