This appears to be a pretty complete implementation of the Logo programming language with a web-based IDE. Logo is derived from Lisp and was intended for teaching programming to children. Typical Logo implementations include "turtle" vector graphics, which was the first chapter in the Apple II Logo reference manual and is probably as far as your schoolteacher got with it.
Why is this a big deal? Does Turtle-Graphics limit the use of 3D rendering or something, Also wouldn't this not be practical for web use? Seems heavy and expensive for rendering purposes to use for initial brand logo use in Web-Development. <Forgive me for not knowing the importance of this shared project> .
