Very cool. It shows clearly how little manual work needs to be done for something like this. The only criticism I have is that, not knowing much about Catalyst, I got a bit lost at points. Maybe watching it again I could put the pieces together, but I wonder if some sort of running commentary would be helpful. It needn't be a voice overlay, necessarily. Even a few pithy comments in an open text window would do the job, I think. But overall, I really liked it!
