never met a *nix system I didn't want to be friends with

WaterCooler

WaterCooler was a free and open-source group chat application designed for use internally within offices and organizations. The intention was to provide a FOSS counterweight to proprietary, SaaS solutions such as Campfire and HipChat, and provide a solution for people looking to host a rich, multi-room chat application behind their firewall on their own hardware.

Built as a way to teach myself JavaScript and Node. I got bored with it, as even in 2013 there were many other, more capable chat system implementations. However, this one might be interesting as a sample application, since it's fairly basic but still has some nice features like @ mentions and embedded media. Who knows if it still runs, though.
