There's a conference in his honour this weekend in Manchester, where he did much of his work. On the list of speakers are Hoare, Knuth, Penrose, Cerf, Kasparov, Fred Brooks, Rodny Brooks, Shamir, and many others. It's quite exciting to get so many luminaries in the same event.
A friend asked me this morning if I fancied the Turing event this evening in Manchester. I'm currently skint and a bit under the weather so I had to pass. Seeing the list of speakers I momentarily felt a lot more unwell until I realised that this wouldn't be the same event!

Edit: It's also quite expensive!
