I like this idea quite a bit. Instead of going starting white and
progressing all 360 degrees to black, though, how about having pure white
represent 0 degrees and progressing through gray to black at 180 degrees and
then back to white? You would then have shades of gray progressing through
90 and 270 degrees mirrored across the north/south line. A counter/variable
would tell you if you were on the east or west side and you could always
have your rcx rotate, say, right and detect if the gray was getting lighter
or darker for a sanity check.
Just a thought,
