This is a pinboard that I have created to show how it is possible to integrate different sites and different information using Google Gadgets and RSS feeds.
There are thousands of Google Gadgets available. Many are pretty awful, but there are some gems to be discovered at http://www.google.com/ig/directory?synd=open
On the right of this, a clock and calendar, and some Google news. More examples are shown below.
The widgets either side of this one show gadgets displaying Twitter feeds. I used the Gadget available at http://www.gmodules.com/ig/creator?synd=open&url=http%3A%2F%2Fhosting.gmodules.com%2Fig%2Fgadgets%2Ffile%2F101874429875337446119%2Ftwit.xml&lang=en but there are several others available that do much the same thing.
The list to the right comes from an RSS feed on my home page of bookmarks to papers I have written.
