First of all, since everybody and their brother seems to be sending it to me right now: yes, I am aware of the online version of the 1898-99 Booth Poverty Map of London. (Apparently BoingBoing precipitated this flood?) My thanks to those of you who told me about it, but you can stop now.
(Not pissy; just a little bemused.)
Second: it’s buggy as hell, but Channel 4 in Britain has put up a flash game connected to their TV show, City of Vice. Both focus on the mid-eighteenth century Bow Street Runners, created by the magistrate Henry Fielding and his brother and successor John, who were arguably London’s first police force. I haven’t seen the show (since it isn’t out on DVD yet or anything, and I’m not the BitTorrent sort), but the first episode of the game is a fun little murder mystery. Unfortunately, the game is prone to hanging at odd points — I discovered a lot of complaints online, when I got frozen during a particular bit — so we’ll have to see if they fix those problems.
Don’t play it without a mouse, though; the bits that require coordination are apparently hell on a trackpad or any other such device.
