An unobtrusive interactive Flickr badge

Being bored yesterday night, I thought that it would be really cool to have a flickr badge that can be navigated (x pictures forward and backward), has a preview in middle size mode (lightbox style) and is generally nicely unobtrusive. I cobbled together some code (dirty at times) and came up with this: Unobtrusive Dynamic Flickr Badge. What it does is turn a simple link to your Flickr stream with a certain ID into the badge, which means that users without JavaScript can still reach your images and you don’t need a server component to pull the images. And guess what, it is not even Ajax! Tell me what you think, and I may find some more time to spice it up with the YUI and make it cleaner.
