This site sells iPod cases made from hollowed-out trashy vintage novels, complete with library cards!
(Thanks, Druidbros!)
Update: Chris sez, ” my girls are making and selling iPod book cases along similar lines but with (1) compartments for all the bits & pieces, and (2) you can listen with the book closed (handy for cloaked listening). Got the idea from a ReadyMade magazine article, plus a few improvements.”
