I've released a simple RSS Reader that uses Cairngorm 2.2. The application is available at: http://nagpals.com/blog/index.cfm/2007/8/28/cairngorm-rss-reader
A few months back I had also released another simple application -- a Cairngorm-based Contact Manager (http://nagpals.com/blog/index.cfm/2007/2/23/A-simple-contact-manager--a-Flexbas\ ed-Cairngorm-application). The key idea behind such simple applications is that they shows the consistency and repeatability of code in applications using Cairngorm. They help in learning the basics of Cairngorm. If you are just starting to work with Cairngorm, following through the code of such applications helps in seeing the patterns that Cairngorm applications follow. I'll hope to do some documentation around the the application some time soon. But till then, have a play! Cheers Indy
