Logo

Logo is a computer programming language used for functional programming. It is an easier to read adaptation and dialect of the Lisp language; some have called it "Lisp without the parentheses." It was created for educational use, more so for constructivist teaching, by Daniel G. Bobrow, Wally Feurzeig and Seymour Papert. http://en.wikipedia.org/wiki/Logo_%28programming_language%29
