I watched this one and I can't stop watching (yes, there are more videos). This has nothing to do with children's books but it does take place in NY (with real people and real reactions!) and it is full of creativity so I'm posting it. It's this stuff that makes me want to create and gets the juices flowing. Go to the website for the rest of them (it's a series). They're great!
