Max,
        I too would be interested in this information.  It would be valuable
and relevant to our new Lifting the Roof exhibit.

Thanks,  Lou Papai

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.
