Dealing with distracting coworkers is difficult no matter what, but this hack uses an old broken NES, an arduino, and some clever coding skills to put together a motion-activated countdown timer that lets coworkers who stop by your office, desk, or cubicle know in no uncertain terms how long they have to say what they need to say before they should leave.

The video above does a great job of explaining it, and while this project may not be practical for most offices, it's definitely fun and creative (if not a little passive aggressive.) Here's how it works: When your distracting coworker comes into your office or sits down at your cubicle, they activate the motion sensor on the NES, which starts a countdown clock. As the seconds count down, the Super Mario theme plays. When it gets to 100 seconds left, the "hurry up" music kicks in, giving your visitor the cue that they need to wrap up what they have to say to you. When their time is up, the Mario death tune plays, telling them their time is up.

The best part of the hack is that the NES plays whatever music you have on the SD card that you load into the cartridge slot, so you can swap out the Mario theme for whatever you like. The Mario theme—complete with the Hurry Up music—is just perfect for getting irritating coworkers out of your hair so you can get some work done.
