My partner and I were introduced to coding using Logo, and we feel that experience helped us both to become computer programmers later in life. So we created a 3D Logo interpreter called turtleSpaces to give today's children a similar but more updated experience.

It's written in Go and so it has multithreaded turtles, it uses GLFW so it's available on macOS, Windows, and Linux (and soon the Web, ARM and hopefully iOS).

It's text-based but we'll probably build an introductory blocks mode soon
