The name of this language immediately made me think of the blocky.io (http://blocky.io/) visual programming language, which was written in Common Lisp by David O'Toole before this language was developed. Blocky.io is very similar to this language, in more then just name, it even has its own MIT scratch like interface: http://blocky.io/blog/wp-content/uploads/2012/03/Screenshot-....
