This extremely short demo video was embedded in the article. It gives a good gist of what it does.

I watched this 4 times and I kind of get it, but it is a horrible demo that ends so fast it’s hard to evaluate what happened.

This seems like it should be a 5 minute demo, from a blank canvas to the turtle.
