CTAN has a new package: dtxgallery
This work is a collection of files that demonstrate simple things that are possible with the flexible and under-appreciated docstrip file format. It is intended as a companion to Scott Pakin's excellent and influential "dtxtut" example of producing LaTeX package's in this way.
This package is located at http://tug.ctan.org/tex-archive/info/dtxgallery . More information is at http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=dtxgallery (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org . Please join a users group; see http://www.tug.org/usergroups.html .
