Many years ago Turtle was a graphic based programming language for childten to teach them programming. With this progtamming language younwere able to move a turtle on the screen, doing anything with this turtle, and so on. It was available for example on Commodore 64. I think this isn't the same Turtle programming language. Am I wrong? 

 I remember the c64 demo scene.  This is a different turtle. 

 I guessed 🙂
