My Cool Book is an interesting information aggregator that displays information in a book format. Users enter in a few keywords (up to 4), and MyCoolBook goes out on the web and aggregates videos, photos, bookmarks, events, eBay auctions, Amazon products, books and podcasts, jobs and more about the topics that you entered. You can take a tour of their sample book about London fashion.

Recently they've launched a new tabbed based interface, that I find much easier to use. You no longer have to turn multiple pages to get to a section you want, you can just click on the tab and get there immediately. Of course, the cool page turning animation is gone, but I think its getting overused these days anyways.
