The LEGI (Geophysical and Industrial Fluid Flows) laboratory (UMR-5519), situated on the Grenoble campus, implemented, in early 2015, a solution for delivering information in the form of multimedia content through large suspended monitors. The aim of the project is two-fold: * to improve visitors’ arrival and waiting time by broadcasting, in the reception foyer, content presenting the laboratory’s research activities: visitors thus receive a quick overview of our activities; * to enhance internal communication via this new medium thanks to the messages broadcast: general meetings, ANR/ERC/Horizon2020 projects achieved, thesis defences and accreditation to supervise research, summer and winter schools, seminars, RSS feeds of supervisory authorities, etc. We provide a look back at our experience with the technical solution selected: the free software Xibo (http://xibo.org.uk/). This solution has the advantage of being a well-controlled architecture whose source code in open and supported by a community of developers. Xibo works in client-server mode. It is multi-screen, multi-zone, fully programmed for dynamic display applications and controlled by a centralised web interface. The server is a web-based application based on the PHP/MySQL combination that can run in a small GNU/Linux virtual machine. The clients run on Windows (free software) or Android (commercial version). The Xibo architecture is robust enough to handle short network outages thanks to the clients’ local cache of all their related data.
