This one has been around the block a time or two, but considering you have absolutely nothing else to do on a Sunday, you might as well dust off that DIY kit and get to work. What you're looking at above is a genuine (albeit modified) NES controller playing a bona fide classic on a laptop. Amazingly, all of the software required for such a marvelously good time is stuffed tight within the controller itself. Take a step back and digest that -- your very own NES emulator (with ROMs), shoved inside a Nintendo Entertainment System controller. Does it get any more awesome than that?
