TeX.sx occasionally inspires people to be ingeniously creative and write cool packages. Let's have a list of all the CTAN packages that originated in a question on TeX.sx.
I suggest a single CW answer for starters, listing the packages alphabetically, following this pattern:
babyloniannum
by Raphaël Pinson (Raphink). Origin: Typesetting Babylonian numerals?
0. [`packagename`](http://www.ctan.org/pkg/packagename) by [package creator's name](link to their profile) (package creator's user name, if ≠ package creator's name). Origin: http://tex.stackexchange.com/questions/number/question(template in the answer source, the numbering works automagically)
If the list ever becomes cluttered, we can consider introducing categories.
This question is the realization of a suggestion to Mark questions that led to creating a new package.
If you notice a package-triggering question that hasn't been marked with the box yet, please add it.
A non-restricted overview of package maintainers on TeX.sx can be found at Who are the package maintainers here?.

from the answers of quite a few questions.[new-package]
for these threads? It would make them easily trackable.
