Worms with path and IK-chains

I saw some earlier topics where ppl have done snakes with just a lattice or path. So I read about this IK-spline that excist in other 3d-softwares and thought that I should try it in blender.
*codec 3ivx D4 4.5.1 is needed.

Edit, new version with divX codec and somewhat improved, but there are still some jerks in em.


I just realised it was better to use a pathbone for every ik-children-bone. Without having the path-constraint bones seperate from the mesh-bones the result will be a slightly deformed snake.
