Odd Job Jack is an animated TV show on Canadian TV, so I've never seen it. The reason I mention it is that they are open-sourcing their production files. FreeJack is their give-away of all of the files used to produce each episode. The whole thing is done in Flash, and they've made available all of their work for others to learn from, borrow, and re-purpose.
It's fascinating to see how the open source movement will translate into other domains. Will this be common, or is Odd Job Jack going to remain the odd man out? In either case, it's great for students of animation who want to see how a show like this is put together. And they've got what looks like detailed tutorials explaining what they do.
The files are distributed over bittorrent because of their size (about 800Mb per episode)!
