Very interesting. Looks like a cross between the App Inventor (blocks-to-scheme) and Alice (fill-in-java). I had a similar project for my dissertation and I also came to the conclusion that working on the AST is vital, so Lisp looked like a great option. But it was believed that it's much to unpopular and scary for anyone to ever manage to use it, so I ended up generating JS from blocks. Didn't work very well at all.
