The Hard Rock Cafe's rock memorabilia site, http://memorabilia.hardrock.com, is a great example of Deep Zoom being used to create an engaging experience with photos of its collection. You can use the same technology to display a portfolio of your own work, where users can instantly switch between thumbnails and high-res images.
For this project, you'll need either Windows Vista or Windows XP Service Pack 2, as well as Silverlight 2 Beta 1. You'll also need to download the Deep Zoom Composer software to create the Deep Zoom from your images. If you want to edit the site produced by Deep Zoom Composer as well, you'll need a webpage editor such as Microsoft Expression Web. The simplest way to get these things is to visit Mike's blog at http://tinyurl.com/3ldvxx where you'll find all the current download links.
