Instructables poster Justin Seiter didn't let a slightly cheesey but expensive Hallmark card with audio go to waste. Using a glue gun, a junky set of old headphones, electrical tape, a utility knife and a mini-cereal box, he created a speaker for his iPod (or any stereo-jack-accepting device). It might not power your home theater, but it gets stereo sound from the headphone wires and might make for a geek-pride spare speaker in a bedroom or bathroom. Hit the link for full instructions on piecing your childhood breakfast favorites and throwaway electronics into modern audio accessories.
