No problem! And thank you for this post! Maybe I should go ahead and hit purchase on Harvey's Logo book series now. There's also another book called Visual Modeling with Logo: A Structured Approach to Seeing that I've ordered that looks very interesting as well. I was drawn in by the description: ***** > Filled with striking illustrations, this book offers an exciting exploration of Logo graphics for designers, architects, liberal arts students, and other individuals who are interested in creative applications of computers. > Visual Modeling with Logo introduces the programming concepts necessary for describing and manipulating some of the basic visual structures in the world around us. Logo is a language that encourages visual problem-solving and helps us expand our understanding of how we see. > The book provides a wide range of exercises for investigating the many dimensions and component parts of seeing; it proceeds from the simple to the complex, using representative models based on circular grids, rectangular grids, Islamic designs, organic forms, and different spatial systems. ***** There's a few others books in a similar vain that I've found too: Learning Mathematics and Logo, Investigations in Algebra: An Approach to Using Logo, and Exploring Logo without a Computer. Then of course there's Turtle Geometry: The Computer as a Medium for Exploring Mathematics. I'm a big fan of books that use programming to explore other topics, and it seems Logo generated a lot of books like this. It's my own lofty dream to write my own series like these.
