I'd like to find a font (or some fonts) that can create a nice little loopy calligraphic design for use in content separation and/or layout touchups.

An example of what I mean is wmdesigns.tff found on dafont.com
http://www.dafont.com/wm-designs-1.font

An example of usage, so you know what the heck I'm talking about, can be found on our very own James Matthias' personal blog site (under the left nav section), leihu.com:

Anyone have any good/decent finds? If I needed to I could create some simple sketches in a vector art program (therefore not willing to pay for any fonts) but seeing examples all prepackaged in a vector format (ttf) is always nice.

Usually they are not part of a font but custom made vectors or parts of a brush set or a symbol set.

Any examples of those?

Why don't you just ask James himself?
