Again, the designers could have simply created a series of pages and stuck text
, sound files and a bunch of pictures on them, but then the site is just that: a bunch of pages with a static display. Through the metaphor of the scrapbook, the site becomes something different. So look for such metaphors in site design. Look how others may use these metaphors in their designs. They not only add to the design of the site, but the add to the usability of it as well.
