:-) This reminds me of the other day when DS was tackling a 3D geometry question and was having trouble visualising it. He decided to make a model with plasticine, did so, saw immediately how to answer the question rigorously, and the next thing I knew he was bringing me plasticine robots and interestingly mottled cut faces of pladticine to inspect.
