The 37signals blog points out a simply Ruby script for KDE that will give you a visual notification when a new message is posted to a Campfire chat room. I have modified that script to work for Gnome as well as KDE, and additionally a text console. I also made a few other additions such as:
- Allow you to specify a specific chat room(s) as a command line argument
- Multiple chats rooms can be monitored concurrently using threading
- Added the Campfire logo to the notifications
- Added some initial status messages to display login status, room topic, and current people in the room
- Display of the last 3 messages of the current day's transcript so you know what's going on without need to login
- Filter out ads

I'm sure you can think of plenty more customizations such as command-line options for all the default settings, etc. But I wanted to keep it fairly simple.
One last thing, here is the cropped version of the Campfire logo I use for my notifications (campfire-logo.png):
