Hi,
I didn’t came to FOSDEM because of a flu, but I prepared a banner for printing. I share it here: https://dl.amie.coop/f.php?h=1IqOQWPW&d=1
cool 
What would really be cool is to have a table cloth with the logo. But then the question is … where do put the logo ? in the middle ? or so that it shows on the side ?
