Elalgallery gave me this amazing book on badges the other day. It's packed full amazing designs and ideas. After spending hours trawling through it I spent ages making up some new funky designs, which you can see here in my facebook album.
The other great thing about the book is that it give the websites for all the designers, so when I was finished dissecting the book I was then able to go online and drool a little bit more.
Here are some of the best links
