> Limited resources is the thing I think that is true. When we didn't have access to a proper football at school, we took used notebook papers, made a ball out of it, put that in several layers of small plastic bags (for water proofing) and tightened that in with a thick string looped to cover the surface. It served perfectly as football for a bunch of noisy kids and was easily replaceable. Paucity provides the spark for creativity.
