Source dictionaries from file?



Hi, all,
first post, bear with me:

I want to write a screen saver similar to the RSS feed shipped in Tiger. However, I'd like to source the array of dictionaries not from an RSS feed, but locally from a CoreData based app. In particular, I think I can easily save the array of dicts into a local file, eg as an archived NSArray (or possibly as XML?)

So, is there a way I can source data from a local file in Quartz Composer?

The alternative seems to be to use the Xcode template to write a ScreenSaver, and include the Quartz framework, load the composition, and go from there. If I create my array of dicts in the Cocoa ScreenSaver, can I bind it to a published port in the composition to access it?

Thanks for your help -
Fab
