This is still early in development. You can see the very raw output at http://www.32hours.com/at10. The goals I have for this application include a Google gadget that will show you a top 10 list of books, and let you click through to get more detail, and purchase.
If you are adventurous, you can add the gadget to your iGoogle page by choosing "Add Stuff," clicking on the link "by url" and pasting in the following address: http://hosting.gmodules.com/ig/gadgets/file/106092714974714025177/at10-32hours.xml. The gadget will update as I work on it, no need to "upgrade"
