1. In these cases, an interactive painting links to specific narratives as the mouse pointer rolls over various characters.

4. First launched in mid–October as a single page displaying covers from more than 3,400 science fiction novels, CoverPop has grown to include one–page collections of covers from Mad Magazine, graphic novels, mysteries, vintage pulp, and women‘s and science magazines, plus a world of Harry Potter jackets. (And if you want a break from the books, collections of ‘nonliterary‘ subjects, such as musical instruments, board games, cereal boxes, and even "500 Gifts For Geeks" have also been compiled.) In each case, the collection is presented as a seemingly random mess of thumbnail images filling the browser screen. (In fact, there is an order to the arrangements, and each page will point out any clues to such layout–dependent variables as vintage, or for collectibles, price.) Rest your mouse pointer over a thumbnail, and a larger version of the image rises out of the mass along with a line or two of information.
