Abstract
In one embodiment, a variable screen includes a first panel including elongated slats having a fixed end and a free end, the slats being flexible so that they can bend without breaking, and a second panel associated with the first panel, the second panel including elongated slots that align with the slats of the first panel, wherein the free ends of the slats are attached to the second panel near ends of the slots and wherein relative movement of the panels causes the slats to bow outward to enable light or air to pass through the slots.
