Was looking up some more info on Maastricht Upper Area Control Center (MUAC) and found [1] this image of a controller in front of a terminal with a Tux sticker on it: http://i.imgur.com/VQFn2hM.jpg
Does anyone have an explanation for that? Are they using FOSS at these centers?
EDIT: Apparently the stickers aren't on every terminal but at least on more than one, as can be seen in this picture: https://www.flickr.com/photos/eurocontrol/5201407322/in/albu...
