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.
