Twitterfall is a tool for tracking trends which is very helpful because the Twitter Search does not auto-refreshes while Twiterfall solves that problem by cascading tweets with popular keywords or custom search so you can always see what's going on without having to refresh the page. You can also log into Twitter to put your friends' tweets in the mix, or just view them by themselves.
The webpage is also customizable and you can choose from different skins, the refresh speed, animation type, rather or not to show retweets and many other tweaks.
Twitterfall also supports direct retwitter from it's page, dm, favorite and reply, if you're logged in. It's practically a new Twitter interface, but more customizable, usable and (dare i say) truly real-time.
