Logo! https://turtlespaces.org/2021/05/21/past-and-future-turtles-the-evolution-of-the-logo-programming-language-part-1/

Good times! I got my start with LOGO on a TRS-80 when I was about five. In all that time my favorite program remains the same:

to doit :r :dr
  fd 3
  rt :r
  doit :r+:dr
end

Here's a Scratch version https://scratch.mit.edu/projects/605658/. (Turns out it there's been some bitrot in 12 years. Had to fix up a few bits.)

Really nice project !!
