Soude

Author easily posed hand drawn puppets.
Soude builds on Soda Constructor's idea of a dynamic & deformable mesh, except you can use a pencil to draw on the mesh, and create what amounts to a dynamic drawing that you can pull, push, move around, and animate. The default mesh is a stick figure, but you can edit the mesh and create arbitrary creatures.
Soude's user interface is incredible simple, and the program comes with plenty of examples you can play around with. A Read Me details Soude's non-obvious features, and explains how it works.
A subset of Soude is used in Comic Book Dollhouse for character graphics.
