You can access them at this location:
~/Library/Mobile Documents/
Each application has its own folder that contains its documents. Files can be added or removed from this window.
(If you need to know how to access your ~/Library folder, here are a couple dozen ways to do so.)
[kirkmc adds: It's worth noting that when you go into that folder, you are actually accessing iCloud; it shows as such in the Finder title bar and path bar. If you move a file from one of these application folders to the Trash, you'll see a dialog informing you that this also deletes them from iCloud, and asking if you're sure that you want to delete them.
By the way, I've created a new iCloud topic, as I think we'll be seeing a number of hints that deal with iCloud, many of which will straddle the iOS and OS X topics.]
