They look really nice.  The way you make them ("the hard way") seems
to me like a LOT of boring work.  Maybe you can automate this process
a little bit by automatically export every frame of your animation to
a POVray file by using the povexport.py module.  This can be done
automatically in your interpolation programs.  After this you can
batch-render all the images with POVray.  This way you will get
smoother images and automate the process by avoiding the boring manual
copy/paste cycle.

Give it a try, rendering won't take long, it will probably be faster
than manually copying/pasting the frames.
