Somehow I overlooked this one earlier when I posted the soft flexible screen. This screen accordion folds back on itself very much like a traditional screen, but the panels are made out of translucent corrugated plastic sheets - like corrugated cardboard in milky white. I actually have one of these in my office and I love it. This was originally produced by Herman Miller as part of their Relay office system, which in its time was a pretty revolutionary freestanding desk system. There, now I've done it - dated myself..
