Fast

 It's a newbie error; even at the lowest framerate, my Sketchbook

animation is much too fast. Need to redo this with many more frames...

*     *     *

Interestingly, one can adjust the playback speed from Blogger. Viewed at a slower

speed, the animation is watchable. The transitions are abrupt...

Here is the same idea, but on Synfig. I have two bee images, one the mirror

of the other. They are in a switch group, so that one only sees the one I ask for

in the properties panel at any time. All the keyframes are clamped, except

for an extra frame EaseIn/EasesOut when I switch images, so that there is 

always a bee visible.

Sketchbook accomodates the visibility of layers more easily, but there is no tweening.

                                                                    

Below, the bee is more jittery, which makes it look more realistic. One

goes to the origin of the image, convert, random.
