Yes, loads of them. I'm not sure I'd recommend any of them though.
What you're literally talking about here (by using terms like
"background") is client-side assembly of a rendered bitmap image.
That's not a good end-result to aim at: it dumps the semantics of text
web documents in favour of pictures, it's inaccessible, and it relies
on the real-time availability of other peoples' servers.
A much better way to do this broad topic of "aggregating content" is
to use server-side processing and to produce final web document that's
still a web document, not just a picture of one. This is standard
aggregation technology these days - use Atom or RSS, either is _far_
easier than trying to scrpae HTML form other sites.
Agggregation also permits caching, so you're not hitting other
peoples' bandwidth so heavily, and you're not so dependent on their
server reliability.
If you want aggregated content as a "background", then SSI to a <div>,
or indeed directly into <iframe> works. Use z-index to control
"layering".
If you really want to, you can render the content to a bitmap (or
aggregate a bitmap) and then use background-image on your page. This
is very easy, but it has the limitations described above. It would all
depend on what you're after - a "browser wallpaper of the day" service
might be cute.
