The only videos I found were the screencasts on the bottom. While fine, these only demonstrate basic features, features that again are available pretty much across the board. What I want to see is them putting together this Mail app from scratch, lets have a real start and a real goal. Now, I know many frameworks don't do this, but thats precisely why it would be a huge win to have. Even we don't do this as well as we should.

Now, if the reply to this is "but the video would take 10 hours!", then unless your counting time to make the art in photoshop, there's a serious problem. If I were to do a screencast of making that Mail.app interface in Cocoa, it would literally be 10-20 minutes max. Its honestly just drag and dropping the components in in Interface Builder, then setting up the bindings and data sources.

For the most part, open source makes the irrelevant. Not that we are going anywhere, but if we dropped off the face of the planet tomorrow, Cappuccino would go on. We already have a thriving community of contributors and users who rely on Cappuccino for their own businesses, many of whom are more than capable of continuing the frameworks development.
