I just visited Bletchley Park last week. It was great to see, especially the Colossus MK2 reconstruction and the working rebuild of Turing's Bombe. The only thing that made me sad was the lack of discussion of the way the government treated Turing; it was glossed over on a sign next to the Turing statue, but other than that, not a word was said.

Here's a sad little video I took on my phone of the Colossus MK2 rebuild in action: http://www.youtube.com/watch?v=ziOEFIBZmBk.
