Old fashion smoke chimney

Recently I help a little bit on almost ready scripted tool (by Danny McAuliffe) that made old fashion smoke chimney (read more here), but Denis Trofimov decide to move this task more forward by writing this as scripted primitive. The author plan to support future development of his plugin with new features, and he's open for questions and suggestions (read more here).

P.S. - I see that Danny McAuliffe add some features to it Chimney Maker and finally upload it to ScriptSpot.
