The skin modifier, which is new in Blender 2.64, has been added to the modifier compendium
. The skin modifier can be used to easily create base-meshes for sculpting or to create abstract or cartoonish figures.
There is really a lot of cool things you can do with the skin modifier. Check out the examples in this thread on Blenderartists and this interesting example-file on BlendSwap.
