Tin drums (containers) become tin drums (muscial instruments).
Bathtubs become feeding troughs.
Bean cans become roofing (flattened and hammered).
Old clothes become quilts, or tents, when pieced together...
Obviously I am thinking too much about BM, much I think this is valid. I'm gonna incorporate (by necessity, due to budget) as many re-purposed things as possible.

Ideas?
