demoparty n.
[demoscene] Aboveground
descendant of the copyparty, with
emphasis shifted away from software piracy and towards compos. Smaller demoparties, for 100
persons or less, are held quite often, sometimes even once a
month, and usually last for one to two days. On the other end of
the scale, huge demo parties are held once a year (and four of
these have grown very large and occur annually - Assembly in
Finland, The Party in Denmark, The Gathering in Norway, and NAID
somewhere in north America). These parties usually last for three
to five days, have room for 3000-5000 people, and have a party
network with connection to the internet.
