Definitely, in fact the image is one frame from an animation. I have done a
number of animations which involve butterflies following spline curves. I
sometimes, as in this image, use a union of cylinders and spheres of some
suitable radius, following the spline curve, and subtract that union from a
large sphere or cube, creating a tunnel or tunnels leading in and out of the
sphere or cube. Then I fly the camera through the tunnels and often the camera
is following several objects. Perhaps one or more butterflies.

I have found tho that I must take care to have many many frames or else the
action happens too fast.

Hence, once again, I need a render farm.
