My boss saw an exhibit some time back of a bridge that you walk on and by
looking through polarization filters you were able to see where the stress
was on the bridge.  We did not get a picture of it but if anyone has a
picture or could direct me to the Centre where the bridge is it would
greatly appreciated.  I have seen an exhibit like this in table top format
but never big.
