Gaim is now Pidgin
It is common for many projects to be renamed, following lawsuits by proprietory companies. Linspire is what comes to my mind immediately.
But it is very rare for a project to be renamed the second time 
Gaim has earned this special reputation. Following the lawsuit by AOL, the GTK+ AOL Instant Messenger was renamed as Gaim.
Now that AIM is trademarked by AOL, Gaim was (force) renamed to Pidgin on April 6, 2007. The libraries “Libgaim” was renamed to libpurple, while “gaim-text” became “Finch”.
The newer version, Pidgin has a lot of fixes and features in it which includes voice/video (I was waiting for this).
Here is the screenshot.
For non-linux users, here is your info. Pidgin is a popular multi-platform instant messaging client that supports many commonly used instant messaging protocols (meaning you can run YM, AOL, Gtalk etc at the same time using one single client). Intially developed for Unix-like operating systems, Pidgin now runs on a variety of platforms, including Microsoft Windows, GNU/Linux, FreeBSD, SkyOS and Trolltech’s PDA system, Qtopia.
