AjaxDaddy offers up a nice collection of Ajax examples, tools and demos. It’s got a varied selection, so if you’re into Ajax, you should be able to find just what you’re looking for. If it’s not there, feel free to add it yourself. Each item comes with a brief but detailed write up about what it does, and how it works; plus there’s a link for downloading the app. Examples are classified by tags at the top of the page. You’ve got everything from fisheye and glide to slideshow and zoom. Demos have a separate tab for themselves. There’s also another separate tag for Ajax books online and for purchase.
