A lively, casual, friendly atmosphere, this is likely what best describes the fantastic IEEE LAN, which took place on November 25 & 26 (2011) in Montefiore. 

A brief reminder: this LAN consisted of a 24-hour League of Legend tournament by team. The small number of contestants made this 24h LoL tournament cheerful. The two best teams came back home with their prizes (a bottle of Champagne for the winners, and a bottle of Asti for the seconds).
