Back in March, I wrote a top-ten list on retro tech that featured the 45 iPod Case from Contexture Design made out of old vinyl 45's. Well, the company is back with the 45 Nano, crafted from cassette tapes! One side of the cassette case is completely hollowed out, shielded by a clear plastic window to access your nano's click wheel, headphone jack, and charging dock. Each case fits the 1st and 2nd gen nanos and features foam padding inside for extra protection.

Contexture is currently in the process of making similar cases for the iPod nano 3rd generation. Each 45 Nano sells for $45 plus $4 shipping worldwide. But hurry, because these retro cases are limited editions!
