What accesories are compatible with the new Iphone 5C?

I bought a 5c recently and want to know what accessories and overall gadgets work with the 5C also id like to know what is the coolest gadget or accessory for the 5C

Not that many existing accessories work for the iPhone 5C because it has a brand new design, so existing cases and some docks may not work with it.

However, some accessories that don't depend on the phone's shape will work, so general docks and headphones.
