This is a small plug-in for the XChat IRC client written in Perl. It allows you to see other people's faces while chatting.
Since it seems that some people had liked my little plugin, I'm going to publish it to the world, it is a first version, hacked in a couple of nights, so I surely has bugs. Any feedback is welcomed.
I put up a page here.
Update: Steve Kemp has pointed me to something similar he did for irssi, for you console-inclined people.
