Mathematical! There's going to be a DS game based on Cartoon Network's surreal Adventure Time with Finn and Jake. Details are few, but weird animated GIFs are numerous, thanks to Adventure Time creator Pendleton Ward, who tweeted the news with a series of DS-relateddrawings. You should go look at all of those.
While posting these great images, Ward also revealed that the "sweet sweet DS game, being made at WayForward Technologies, will come out later this year." We're contacting WayForward to learn more, but we can already declare this news rhombus.
