Blog Flair

I am wanting to put some blog flair on my sidebar with my Currently Reading book
list.  I have looked through Amazon, and through a few other sites, and I simply
cannot find an out-of-the-box JavaScript based solution for this.

Surely someone in the world provides a service where I can administer blog flair on
their servers and then link to it via JavaScript, thus not forcing me to write code. 
If this service does not exist, perhaps I should create it!

Anyone know if one?
