So, you've got $2 burning a hole in your pocket and you want to calculate money you only wish you had? Well DSi users, you're in luck with a nifty calculator. But, the convenience doesn't end there. The application utilizes sound effects and visuals from Super Mario Bros. If you think about it, it's a really smart idea! For years we've been joking that the DS prints money, but now the DSi can count it, too. Oh, technology ... where would we be without you? Check out a video of the application in action after the break.
