Contexture Design, best known for its custom cases made out of vinyl records, has taken a different approach in building for the first- and second-generation iPod nano. The company's 45 Nano cases are altered cassette tapes, hollowed out to allow just enough space for the player; foam padding helps protect against impacts. Added on the front is a clear plastic window, with special cuts to allow access to controls, the headphone jack, and the dock. The product further comes shipped within the tape's original case, for extra protection. 45 Nanos are being sold online for $45.
