Well, there's some work behind...
First of all, I had saved a clip called "robot mommy movie".
I selected some frames with the program Free Video to JPG Converter.
I manipped a couple of frames - similar to the two here attached - inserting the "neck" picture; by the way, it's been necessary to adjust brightness and contrast...
Finally, I made a gif with those two frames and others unmanipped !
Cheers
Aldo
