I know this is not what you are looking for, but I just wanted to take advantage of your post to remind the HN crowd of the fact that the magnificent book Turtle Geometry: The Computer as a Medium for Exploring Mathematics is available in Open Access at : https://direct.mit.edu/books/oa-monograph/4663/Turtle-Geomet... . One of the co-author is no less than Harold Abelson, who is also a co-author of the (in)famous SICP.

If you are looking for a book a little less hardcore than the previous recommendation, check out Visual Modeling With Logo: A Structured Approach to Seeing by James Clayson.
