Blogger Play will show you a never-ending stream of images that were just uploaded to public Blogger blogs.Please note the warning:
A caveat: we use many techniques, including Google’s SafeSearch technology, to keep the images clean. Nevertheless, on rare occasions an image that you may find vulgar or obscene will slip through our algorithmic filters. Google does not pre-screen the images that appear in Blogger Play, nor is it responsible for their content. To report a terms of service violation, you may fill out this contact form.
It's kind of interesting to watch - kind of a social networking voyeur thing. I was thinking it might be an interesting source as a writing prompt (I especially like that you can click through to the post that contains the picture), or as some kind of social research project.
