About Vowl
Give Vowl a list of tags, and it displays an unattended slideshow of random Flickr photos matching those tags.
By default it shows you "cat", "dog", and "chicken" photos, but this can be changed in the preferences.
You can also customize the delay between each photo, and whether or not Vowl floats above all other windows.
If you click on a photo, Vowl will open that photo's Flickr page in the default web browser.
That's it. That's all it does.
