visualisation on the ongoing (and open) IRC conversation
I had the mail of Markus from David Gautier at CIID (Massimo and I were working there) but Markus pointed me to the IRC Channel of the place. No need to install clients. No need to know what IRC is. Just logged in and started chatting with people and setup for the meeting. This chat is visualised on 8-10 screens all over the place. Nice.
