e.g.
repeat 8 [rt 45 repeat 6 [repeat 90 [fd 2 rt 2] rt 90]]

While you can draw beautiful logos with simple scripts, the main problem is that the pixels of the rendered line art are coarse. (It’s not that coarse, but if you zoom in a bit, you can see it’s coarse.)
Whichever interpreter you use from the above, it’s not something that can be used for business purposes, perhaps because the original system was designed for educational purposes rather than commercial use.
However, I think the language itself is very interesting and intriguing. Since the resolution issue seems like something that could be easily addressed, there may eventually be an interpreter that can generate high-resolution images.
