This is really interesting, and pretty exciting to me. I've heard so many good things about SICP and yet it has been phasing out of use in courses. The potential for a course/book that takes SICP and improves on it is really neat.

Also, there's a really interesting bit toward the end that I'd like to call out for those who might not have read that far:

"...Still, the htdp curriculum has had an interesting measurable effect concerning female students. Several instructors reported that female students like the HtDP curriculum exceptionally well. In a controlled experiment, an htdp-trained instructor taught a conventional AP curriculum and the Scheme curriculum to the same three classes of students. Together the three classes consisted of over 70 students. While all students preferred our approach to programming, the preference among females was a stunning factor of four. An independent evaluator is now investigating this aspect of the project in more depth."
