Sights and sounds of retro Famicom keychains
For the price of $13.50 you can get a keychain featuring cool, retro blocky graphic coupled with a miniature Famicom controller that makes character-relevant sound effects, like this especially obnoxious one from Ice Climber (wav).
I couldn't imagine having one of these in my pocket, repeating that sound effect ad nauseum every time something hit the "A" button; the pixelated portion is aces though.
