This one of those simple and obvious models that leaves me thinking. I came up with the idea very recently (I can't beileve I had not thought about it before). I'm really proud of the box; I love the fact that none of it's sides are square despite the fact that you start from a square piece of paper (I'm easy to amaze... haha). Being so simple and obvious maybe someone else had already came up with the idea before me. I browsed a bit through the web but I didn't see any similar boxes. Do any of you know if this box already existed?
