In order to change the color palette ever interlaced scan line, dynamic modes use both the copper and the processor 100% of the time. This means that multi- tasking must be shut off. As such there is no processor available to decode the next frame of an animation. If the images are already in memory (limiting greatly the number of frames) it might be possible, but the added overhead is most probably too much for a 68000 machine. It might be possible with an accelerated machine (or 3000) but even then it would be tough. SHAM images utilize only the copper and can change the palette every other interlaced scan line (or every non-interlaced one), and that may be a reasonable format to attempt animation in, but I don't know of one yet (BTW, overscan makes even SHAM overhead prohibitive, not for the processor but for the memory bus).
