Abstract: A wind screen uses flexible sheets of porous material. The sheets include attached stakes at regular intervals. The stakes are stackable so that a wind screen of arbitrary height can be easily constructed. In one embodiment, the sheets can be cut so that the horizontal length of the screen can be easily modified. The flexibility of the sheets and the spacing of the stakes allow a human user to position the windscreen in any arbitrary design or shape, as desired. Assemblies are disclosed whereby two or more stakes can be stacked onto a single stake.
