Once bitten....?

You may have heard of the building in London which, because of its glass-covered concave shape, is reflecting and concentrating the sun's rays and causing severe scorching at the focal point - apparently it's blistered paintwork, burnt carpet and even fried an egg.  Whoops, you may think - until you find out that the same architect designed a similar building some years ago in Las Vegas, with exactly similar problems.  Talk about learning from past experience??
