Google's doodle for November 23rd is fairly fun — it's a little animated puzzle game in honor of the 60th anniversary of science fiction author Stanislaw Lem's first book being published. The doodle itself is inspired by The Cyerberiad, a series of short stories Lem wrote about a robot universe. It's up right now in the Europe, we'd expect it'll be charming people across the rest of the world as time goes on.
