compo
n.
[ demoscene] Finnish-originated slang for ‘competition’. Demo compos are held at a demoparty. The usual protocol is that several groups make demos for a compo, they are shown on a big screen, and then the party participants vote for the best one. Prizes (from sponsors and party entrance fees) are given. Standard compo formats include intro compos (4k or 64k demos), music compos, graphics compos, quick demo compos (build a demo within 4 hours for example), etc.
