Images: The next great iPod accessory?

Dozens of ideas for new iPod accessories hang in the Macworld booth of Mophie, a small Vermont company that specializes in add-ons for the Apple music player. The company held a contest soliciting Macworld attendees' design ideas. It received 150 ideas in about four hours at its booth on Tuesday, January 9. A quick round of online voting helped the company choose three finalists. The company then had the three ideas made into prototypes by that Friday.
