iYo YoYo - The yo-yo charger for your iPhone and iPod
Swedish designer Peter Thuvander has come up with the iYo YoYo, a nifty green alternative way to charge your iPhone or iPod.
Thanks to a small Li-ion battery inside the yo-yo you build up a charge while you play with the iYo YoYo. Afterwards you can just plug in your iPod or iPhone and it will be charged.
