In the beginning ...
... the logo turtle was a robot turtle connected to a computer - this was 1967! The turtle carried a pen which drew a line on the paper it was resting on as it moved. Commands were typed into the computer to make the turtle move. The language used was called "logo". The driving force behind all this was Seymour Papert at MIT. Today Logo has been largely replaced by Scratch, also from MIT.
Now it's 2018 and I've decided to revisit this amazing idea which basically offers a very short list of commands like forward, back, left, right, penup, pendown, repeat. This project is an attempt to demonstrate the considerable power this offered the young programmer.
