You know what's a good cure for office boredom? A Mac app that changes parts of your screen into a playable level straight out of Super Mario Bros. Thanks to Aaron Randall's Screentendo desktop add-on, a similar process to that of taking a screenshot can have you playing a unique Mario level in seconds. In this case, game building is a two-step process that first determines the underlying structure of the image before generating those bricks on top. Randall admits that the app isn't without flaws, and that it's more of a proof-of-concept than anything else. For example, the image rendering works best on images with high contrast -- like the Google logo captured in the video after the break.
