This time, my students and I were learning to build a spinning stool in Nanoland sandbox. (We love this sandbox so much because it's open to public, it has no time limit, and it's in educational sim-just a few meters from the Nanoland museum) They learned to make an accurate allignment and copy of an object. They also learned to use the rotation script. My friend Diraitout, a teacher from Belgium, observed our class for our future collaboration. Meine Stundenten sind schlau, nicht wahr Diraitout?
