I really liked this site since it not only discussed flow in design, but also tied in (refreshed the mind on) past topics which we have covered in class.
I felt seeing repetition (the example is towards the bottom of the page) in something apart from a picture or on paper was helpful. Seeing it put to use in the form of landscaping was neat to me.
This sight helped me out by showing different examples of symmetry in web design. I also liked how it gave little explanations of the types below each picture.
The general construction of this page does a marvelous job of using contrast to liven up their page, as opposed to a more traditional news page which usually doesn't offer too much in way of color of format variation.
I found this to be a different way of looking at how to emphasize points, illustration (painting, graphic design, etc) is a really colorful way to highlight an idea.
