Animated logo for Amazon storefront

I\'m looking for a logo for my Amazon Storefront. I am looking for an animated logo. The storefront name is \"The Book Shark\", I will let you use your imagination. According to Amazon, the logo limitations are 120 pixels (width) by 30 pixels (height) although i have seen larger ones, and gif/jpg file format..

I have a second storefront and if this one works out, then a 2nd logo may be purchased.
