Also known as "Furulund Party" and "Hacker Conference". Despite the name, it was not a "hacker conference" but an ordinary copy-/demoparty. In order to make their event appear more professional, the party organisers prohibited copying pirated software - a regulation noone stuck to. (Info by Knatter/XAKK, 2015-05-31)
