IGN: Mario Clock Review
Released on the same day is the Mario Calculator, a much more useful application that combines the power of a number crunching calculator and a unit converter with the branding of an 8-bit Mario game. There’s no game here, just the ability to add, subtract, multiply, and divide, as well as figure out how many miles are in a kilometer, or how many human years in a dog year. But all the data entry is put to the sounds and animation of Super Mario Bros. for the original NES. Be sure to turn the sound down on your system if you’re using it in class.
