I missed this awesome casemod when it made the online rounds a while back, but thanks to the magic of Tumblr, I've discovered Ryan Luke Johns' clever iBoy design. As diagrammed above, it's got the hardware of an iPod wrapped up in a classic Game Boy case, with a dock connector cleverly inserted such that the Game Boy buttons correspond to iPod functions.
The iBoy is an iPod case with an internal dock connector—allowing the user to control the iPod with the buttons of an outdated Game Boy. Complete with a functioning speaker, hold switch, and headphone port, the iBoy is a user-friendly theft-deterrent.The iPod has evolved and segmented quite a bit since Johns designed the iBoy in 2006, but this would still look pretty boss with an iPod Classic.
