You have to light sources in it, one of them should not have shadows.

Sure, if I wanted to do a realistic outdoor scene.
In this case I did not :).
I wanted my source to be as simple as possible
and only show the use of my macro to animate
this butterfly.
Hmm, in retrospect, I think I should have used
one light and ambient lighting. That would have
been even more basic. Thanks for pointing out.

Next you should try making a looping animation with some acceleration and
deceleration near the end points.
#macro animSin(C) sin(2*pi*C)
#macro animSin01(C) (animSin(C-0.25)+1)/2
I assume you have some place in your code that does:
rotate <0, 0, 90*clock>
try:
rotate <0, 0, 90*animSin01(clock)>
oh, and double your frame count, if you do this.

That is an interesting way to make a cosine ;)

No, I have not (see source in pbs-f)
I am afraid it was a lot more work than that.

No:
Atalanta(animSin01(clock))
It looks reasonable. I am sure the wings do not
move like a sinusoid, but my brain does not
object to this movement as unrealistic.
I probably would have tried something more
complicated then a pure sinusoid myself, so
thanks for preventing another level of complexity.

No to make it even remotely behaving like a butterfly
I have increase the framerate and then at 32 frames
30 frames per second it still is in slow motion.
Thanks for your comment.
