Been having fun with animated GIFs, but thought I'd better not clutter up Mike Engles' Further Challenge thread any more, so I've prepared this little recipe in case anyone's interested:
Draw a circle.
Apply a brush (mine was a single American Uncial letter 'p' with linear fill from red to yellow).
Frame 1 (100cs)
Maximum brush spacing to place the letters at 12, 3, 6 and 9 o'clock.
Frames 2-6 (20cs each)
Brush rotated through 30° per frame.
Frame 7 (100cs)
Another 30° takes us to 180°, and two of the 'p's have become 'd's!
Frames 8-12 (20cs each)
Brush rotated through 30° per frame.
Frame 13 (100cs)
Another 30° brings us back to our starting point.
Frames 14-23 (5cs each)
Rotation stopped and spacing reduced by approx. one division of the slider per frame to make the 'ring'.
Frame 24 (100cs)
Which becomes complete upon reaching the minimum spacing.
Frames 25-35 (5cs each)
'Rotate along path' either re-enabled or left unchecked (see illustration) and random offset increased from 0-100% at 10% per frame to create the 'fire'.

Animated GIF exported with global optimised 256 colour palette. (You'd think that fewer colours would work when it's all in the red-yellow area, but the fill quickly starts to look 'stepped'. So it's 10K for the .xar file and 128K for the GIF...)
Changes to saturation, hue and scaling all look like fertile ground for brush-based animations, but maybe another day...
About the only thing that still bugs me about this one is the 55cs duration of the 'fire' when everything else adds up to 50 or 100cs units, but it would be silly to change things just because of some misguided loyalty to round numbers! Oh, and I can't decide which of the two 'fire's I like best...
