While passing through London Kings Cross i had an annoying "wait" for my train, so I decided to put it to some good use. Withing walking distance of the station is the British Library so I decided to be a tourist and have a look. Inside the building there was a sign that said "The Turing Institute" - which although closed to the General Public had this interesting piece of history on display (see below, an Enigma Machine [or mock-up]):
Another interesting feature is that in the British Library (more museum if you ask me) it is very hard to get your hands on a book (unless you buy it) as you need to register for a "Readers Pass" and then I believe they go get it for you. No browsing. So I just used their free WiFi and had an expensive London coffee and bought a book but more of that later ;)
