Curious not to see the term rotoscoping mentioned. As a lot of what is shown in copying some pictures is effectively that, isn't it?
Rotoscoping is specifically tracing over a sequence of images - usually video or film frames - to create a sequence of drawings that can be used in an animation workflow.

Spaceballs’ State Of The Art and 9 Fingers are a couple of Amiga demoscene productions that relied on rotoscoping.
