Here is a cool design for an iPhone charger from designer Mac Funamizu, the iPetals Solar iPhone Charger.
The iPetals Solar iPhone Charger is designed to be portable, and it can be unfolded into a flower shape, where each of the petals features a solar panel, which is used to charge the iPhone.
The petals can be folded away to make it more portable, and it can also be used as a dock to stand your iPhone in.
Very cool, i really like the design, I am sure some manufacturer is bound to pick this up as it would be a cool accessory for the iPhone.
