Well, there seems to be another 5 more ways to browse Amazon according to this article from Read/WriteWeb. They mentioned the following 5 sites: LivePlasma, Flowser, BrowseGoods, Tuneglue, and Coverpop.
I must say all the 5 alternative ways of browsing Amazon are really interesting and visually simulating though it can be a little overwhelming for some of the sites. I particularly like LivePlasma and Tuneglue mainly because of the graphical linkages that they provide on-screen. However, both these two services only either provide access for music and movies (LivePlasma) or just music (Tuneglue). They look a little like mind maps to me. 🙂
But I must put in a special mention for Coverpop. According to the website, the site is more an experiment in art than an e-commerce project. When you click on a particularly category, it generates a collage of the covers of products within that category. Clicking on the one you’re are interested in brings you to the product page on Amazon. They also have non-Amazon collages such as the ones from YouTube and Flickr, which you can explore.
