Everyone has them lying around. What to do with them? Post your creative uses for old card boxes. I discovered that a 2nd Gen or 4th Gen iPod Nano fits perfectly into a box. Also, the clickwheel lines up perfectly with the bottom circle on the back of a box of Bicycles (for the 2nd Gen, the 4th Gen is lower) and it is sensitive through the cardboard. Add some packaging material and some cards for back support, then cut a hole for the screen. There you have it, a handy iPod case.
