To put in a language easily understandable on the Internet, this goes a little something like this: Yo Dawg, I herd you like iPods, so I put an iPod in yo -- Okay, you know what? I'm sorry. Let's not do that ever again.
RecycledGamer made this custom iPod by putting an iPod Mini into a classic NES controller. The result is pretty cool mod.
Visit the Flickr page to see more pictures and learn how it's done.
The NES controller's simple rectangular design makes it perfect for art projects. So far I've seen the design used as a belt buckle, a coin purse, a PC, an Apple remote, and most impressive of all, a fully-working coffee table/storage box.
