San Francisco Symphony Lots of lines here, but you have to concentrate to see them.
Lines definitely take a back seat to the images, but they have control of the page.
Lines direct the flow, and subtly fill in where empty space would be too harsh. In fact, the line use is so good, that while much of the screen is filled with detail, you still feel that the design is clean and open. We often forget how effective a line can be when the color is only a shade or two removed from the background color. This site should inspire you to use subtle design lines in your work. The Saab site is very clean with excellent fine line use.
