Christmas is over, but for those who can’t get enough — or for those who hate the holiday so much that they wish it would be devoured by the ultimate horror — the Penny Arcade guys have a treat for you. The Last Christmas is an animated storybook for the iPad, based on a comic that first appeared in 2004. Basically, it’s a reverse twist on The Night Before Christmas in which Cthulhu arrives and eats everything in sight. It looks like a children’s book, but the horror/cuteness combination is really aimed at adults: In the iPad version, which is lightly animated, tiny skaters fall from the ice after Cthulhu pops up in the middle of it, and lights twinkle on a tree as he devours it (and the screaming hordes run in horror). The app is only a few pages long, and it’s free; the last page is a pitch for donations to Child’s Play, the charity established by Penny Arcade creators Mike Krahulik and Jerry Holkins, which sends toys, games, and books to children in hospitals worldwide.
