Shuffle Saver (Flickr Screensaver)

One of my favourite Flickr related Things is the Flickr screensaver Shufflesaver.

Shufflesaver allows you to view a slideshow of Flickr photos from a person (or narrow down to that person's favourite photos), or you can look for photos specifying up to three tags. You can view photos from everyone's latest photos, or from everyone's interesting photos. You can also select photos from your iPhoto collection if Flickr doesn't appeal. There are various slide tramsitions to choose from and you can set the duration for slides to stay up.

There are also options that allow you to save the current slide to a folder on your hard drive, or iPhoto, or to open the photo's page in you web browser (this doesn't disturb the screensaver, it happens in the background).
A feature I would like is the ability to get photos from pools, or from one or more of a users sets - or perhaps from various sets of various users - then it all gets a bit complex, but at leat the ability to get photos from a pool - so I could see photos from the Fruit and Veg pool, for example.
