3D Logo Experiment

Choose a sample and modify it, or write your own code.

This experiment is inspired by The Coding Train’s Coding Challenge #121: Logo Interpreter. It’s a simple Logo-like turtle graphics implementation, but in 3D, with the additional command, up. It’s written in JavaScript, and the language used by the user is JavaScript, rather than Logo. There are just these commands: fd, rt, up, and repeat.
