If you are out shopping for a Nokia 7310 Supernova Cover then you should check out the new Nokia Build. Nokia Build is a flash based interface that allows you to design your own cover for a 7310 mobile phone.
The flash interface uses simple drawing tools and pre defined templates, images and clipart to allow you to put together the design you want. Right now it is available for France and UK users.
You can find the Nokia Build interface here and design away. It shouldn't be too long before the interface is available in the US too.
