these (older) corridor connections always remind me of old cameras.
do you remember them? one pushed a button, and a lid opened with the lens and a tunnel of black, folded cloth.
it should be doable to copy these.
folding a wet cloth as desired, drying with a pressing iron, then painting with black laquer paint.
(if you don't know, how to fold, ask Mel, he seems to know about Origamy...)
