Interesting comment, FGD135.
This was the subject of a study (studies?) of analog indicators on electronic panels (radio dials, etc.) - maybe 50 years ago. In that case, it was:
o Moving pointer against fixed background scale - vs.
o Fixed index pointer over a moving background scale.
I do not remember the overall outcome, but each had its own pros and cons. For quick comprehension, however, the former (older technology) was deemed superior.
I guess there is nothing new under the Sun.
