Desktop Repainter is an App that can be purchased in the Mac App store, and it colors your desktop, slowly transitioning from one color to the next in a set created by the user. The app was created by a friend, and this site was not intended to serve as a real webpage for the app, but a way of teaching students about web design.
The concept of the page comes from this excellent video from a presentation given by Tim Brown at a conference in 2010. In his talk, he extols the virtues of using type as a foundational building block for relationships in design. He goes on to discuss ways of building relationships between different elements on the page based on these foundational type relationships.
This site was created as an example of his ideas, and is used with my intermediate web design students.
