The doodle is both animated and interactive, with the central character being a robot that looks a lot like Lem. The artwork was inspired by the Daniel Mroz illustrations for Lem’s work The Cyberiad.
A few spoilers/things to look out for: the doodle is actually a lot more interactive than it first seems. Robot eyes will follow your mouse cursor, you can make the bird and cat fly or run away by clicking on them, there’s a chance the bird will sit on your mouse cursor if you stay still long enough, and the “N” object that appears near the end changes every time you complete the doodle. There’s even an extra incentive for completing the doodle three times in the form of an extra finale taken from another story.
