I found this on stumble-upon and figured it was a pretty good resource to use when your looking for inspiration or tips with programs. The site includes graphic design, typography, freelance, image source, and many more links to useful sites.

I also stumbled on this site. Fedrigoni are a
well established, Italian paper company who have refined the art and
science of making fine quality special papers. The challenge was to
create a campaign which will ensure the entire UK design industry hears
about the paper selection tool, consisting of 262 various paper samples
which enables designers to choose the best shade and most suitable
surface for their very next project.
