"Rich problems" make the best Logo projects. As your students (and you!) write Logo procedures that translate their patterns into computer activities, ideas for projects spring to mind. As you work on these new challenges, "idea reproduction" continues. Investigation into these broad areas of interdisciplinary, intrinsically fascinating inquiry reveal what Papert calls powerful ideas. The subject's inherent patterns provide the pliable mess of material; Logo's structure encourages "messing around" in search of patterns and structures.
