Here are two “eyecandy” extenstions for firefox:
The first is PicLens (also supports Safari). Which is a really nice way to view a group of pictures, it displays them in this 3D wall. It supports Flickr, Facebook, Google, Picasa, and a bunch of other websites.

The second is Tab Effect. It adds an effect when you change from tab to tab. Cool, not useful at all, but cool, so its good in my book
(will only work in Windows because it uses DirectX) .:.Link.:.





The first one seems cool but the second one seems like it would cause it to crash or become slow!
it works well with my work pc which is pretty basic
