Ok, this maybe out there but it just an idea. I thought it be cool if there were a set of tools to create a bone structure or maybe a sort of morphing tool. The application could go beyond just characters but perhaps could expand the capabilities for some unique art.
Illustrators and Animators could use this after they create character to move and pose a character or simply make slight adjustments to their character pose. then they could maybe save that as a morph target similar to a snapshot.
Graphic Designer could use this tool to take certain graphic forms or shapes and push and pull solid forms into an organic shape for instance if you wanted to make something look gooey from a flat shape you could place a pin where you don't want things affected and place move point with a fall off adjustment to make that stretchy form. Sure you can draw this form but it be more organic to push and shape the form.
Just had a thought if you have this morph target or snapshots recorded you could use them to create the points for some basic animated Gifs exports.
I should referenced the puppet tool... (I am sure you will do it better) ;)
