You can get the patterns in two ways:
Download all the patterns in the Libre Patterns repository
git clone git://gitorious.org/libre-patterns/libre-patterns.git
You are very welcome to fork it too and modify the patterns to your liking and needs. You can use the template to create similar patterns yourself using LibreCAD or Inkscape. If you create anything of value – do not hesitate to make pull requests for it to be included in libre-patterns.
If you want a copy of the blog contents – just ask or make one with:
wget -m -a html,png,jpeg,jpg http://denizo.opia.dk/libre-patterns/
This will download all contents to your hard drive as browseable xhtml files in folders.
