I've found that despite the wide range of bars available, that it's often hard to find a suitable bar for particular pages, especially pages with subtle natural colours on which bars with names like "fractal orgasm" would be likely to appear conspicuous.
Luckily, it's easy to make up your own bars from photos used in your pages. Here's how.
Hop into Graphic Converter and open one of the more interesting photos you have at your disposal. Rotate the photo 90 degrees if necessary so that the long edge of the image is horizontal. Then select and crop to the most interesting horizontal section of about 4 pixels high that you can find. Use Graphic Converter's scaling feature (X axis only) to scale the section so that it is 600 pixels wide (and still 4 pixels high). You may wish to adjust the brightness and contrast of the bar. I've found that 600 pixels is a good size for a horizontal bar. However, you may wish to experiment with the height. Sometimes a one or two pixel bar is best.
The result is a bar that reflects the colours and structures of the photographic content of the web. I've found that this technique works very well. The viewer may not quite know what the bar is a section of, but they can sense that there is some structure in it, and the colours will have a subtlety that's hard to match in artificially generated images.
Supposing that we had the following image on a page:
We might use it to create the following bar:
