The Centre for Mathematical Sciences building now has information screens at the entrance to the Central Core, another facing in to the core, and displays in each of the pavilion common rooms. These screens are mostly used to display information about talks and seminars taking place in or around the Faculty of Mathematical Sciences site. The information is obtained from talks.cam which has much helpful online documentation.
If you would like an important/urgent message displayed on one/all of the screens then please mail help@maths.
