In traditional typesetting for books, there are often little figures called vignettes that serve as a separation between sections or subsections.

One could always include the graphics as in a figure/vector, draw it with 
tikz-pgf or even work a font, but I am wondering if there is any package that provides good integration with (hopefully pretty) vignettes.

If not, a good collection and instructions to put them automatically at the end of a section will be much appreciated.

**Edit**: Summary of answers: there is no package or way to doing that automatically, at least not touching only the preamble. The best way is to create a macro to insert the ornament and calling it wherever is needed.
