In my school days, I was taught a simple graphics programming language LOGO
I always wanted to make something as cool as it, so I wrote a simple in-browser interpreter for it.
As of now, it is very simple with only the basic functionalities.
But before I improve it wanted to get the feedback of fellow campers.
Try these commands -
fd 40 rt 90 repeat 360 [fd 1 rt 1]
Hope you like it.
