Son of Timatollah

Below, from Meryl in a Barrel, via this post at Boing Boing, is a Jack o'Lantern carved with the image of computer science god Alan Turing. Turing helped break the Nazi codes generated by their Enigma device and laid foundations for the very ideas of artificial intelligence. He was a gay man who lost his security clearance and endured forced hormone "therapy" because of that, eventually committing suicide, total drama queen style, by eating a poison apple.
