I like this website so much

Today when I look around on line and try to find more and more resources for my writing assignment, I found the article named the principles of design (available at http://www.digital-web.com/articles/principles_of_design/). At the bottom of the article, there is a "related resources on the web" section. And the first resource is
: Art, Design, and Visual Thinking by Charlotte Jirousek

If you click on the link, you goes to this website: http://char.txa.cornell.edu/

the theme of the site is :" Art, design and visual thinking. It's a good place to learn basic rules of graphic design.
