This is actually simpler than I thought it would be, but
still had a few "gotchas" in it.
First thing I simply imported a piece of artwork from Illustrator
into Flash 4.
I then created a symbol of the artwork.
The first part of the revolution was easy. Just take the
duplicate the symbol on one frame and then apply a
horizontal scale so
that it was extremely thin on the second frame. Then
it was simply a motion tween between the first and second
What was complicated was getting the symbol to turn
around to a reversed image. I found that if I used
symbol from the original first frame, the image would
rather than just squish in and out.
So I had to create a second symbol of the same image,
but flipped horizontally. I was then able to make
a second motion tween
tween a very thin version of that flipped symbol
symbol in a normal width.
Finally, I simply copied and pasted the first two
frames in reverse order to finish the revolution.
