Firefox 4 and Chrome 6 have support for Websockets. I wrote a websocket server that forwards Recent Changes to a web browser, in order to visualize them dynamically.
Here is a list of pages using it: *[http://toolserver.org/~thomasv/rcsound.html a page that plays a sound everytime a page is proofread at the most active wikisources] *[http://toolserver.org/~thomasv/wprc.html en.WP's recent changes] (it scrolls kind of fast) *[http://toolserver.org/~darkdadaah/wiktio/outils/rc/fr_wikt_rc_table.html fr.wiktionary's RCs] If you decide to write another page that uses this server, please add it to the list.
It is possible to use this tool directly on any Wikimedia wiki ; here is a script that turns the RC page of your wiki into a self-updating page:
importScriptURI('http://wikisource.org/w/index.php?title=MediaWiki:DynamicRC.js&action=ra...');
I hope you enjoy it. If you decide to write a page that uses this tool, please add it to this list : https://wiki.toolserver.org/view/RC_Websocket_server
