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.
