Yeah. I recommend it because it goes way beyond the stuff another commenter complained about in this thread:
> A dozen articles about the language, with listings. The screenshots? All the same, showing recursive pictures of rectangles and circles. Great. LOGO can do that. But what else? Big empty void there.
E.g. the last chapter is an intro to general relativity, with a simulator for motion in curved spacetime.
(CS Logo Style also covers many topics, but it looked like they were all familiar to me as an experienced programmer. I haven't seen another book for programmers about most of the math in Turtle Geometry.)
