That reminds me of a picture I just took in December at Legoland - the Grand
Central Station in Miniland had an amazing bit of damage due to sunlight!
Check it out at http://www.brickshelf.com/cgi-bin/gallery.cgi?i=132159 (big

are getting on the escalator. First you'll see that the reflection of the
clear plastic window has significantly 'boiled' the bricks below, (okay, I
know it didn't physically boil, but it looks like it!) and you'll also see
that the wall has shrunk to such a point that it detached and bowed.
