demogroup
 n.

    [demoscene] A group of demo (sense 4) composers. Job titles within a
    group include coders (the ones who write programs), graphicians (the ones
    who painstakingly pixelate the fine art), musicians (the music composers),
    sysops, traders/swappers (the ones who do the trading and other PR), and
    organizers (in larger groups). It is not uncommon for one person to do
    multiple jobs, but it has been observed that good coders are rarely good
    composers and vice versa. [How odd. Musical talent seems common among
    Internet/Unix hackers ?ESR]
