I have my concern/reservation about Lego, Minecraft that every kid loves. No doubt, they can help to increase kids spatial understanding. But everything is made of a cube, it is rigid without life.
I love the curve, the real beauty of this world that I can touch and feel. Now everything has been put on Second Life, people get rich because of it. I love nature, the one I am currently living in, not the virtual world, not the one made by 0 and 1.
