This isn't about the plumes exactly, but about the display (now replaced) you had posted.  How do you make that neat date display 'icon.'  I'm describing it from memory, but I think it looked like a distorted oval clock face (apologies to Dali fans among you) with months instead of hours.  I'd like to replace scrolling numerals with something like that in animations.  Thanks.

Hi Barry,

Animations like the one you refer to are made from individual 32-day
composites that are advanced eight days for each step.  With this in
mind, I created 46 template images (attached below) with the months
arranged as you see and the given 32-day period highlighted in yellow.
(I chose yellow and the June-at-the-top arrangement to reflect the
apparent movement of the sun from north to south and back again
over the seasons.)

With these templates, I can write a short perl script that uses the
programs giftopnm, pnmtopng, convert, and composite to add the
specific date range to each template and to place each "date dial"
on the appropriate frame of the animation.  I am also attaching the
perl script I used (annotate.pl) for the Madagascar sequence.

I hope this helps.

By the way, you can still view the Madagascar plumes here.

Cool!  It helps a lot and I'm anxious to try it out for a meeting next week.  Thanks and have a great holiday.  Barry
