A Demo is a program that displays a sound, music,
and light show, usually in 3D. They are 100% not
interactive and are only ment to be watched (opposing
"Game Demos" which got nothing to do
with the demoscene).
Essentially, demos "show off". They
do so in usually one, two, or all three of three
They show off the computer's hardware abilities
(3D world & objects, Multi-channel Music,
They show off the creative abilities of the demo
group (Artists, Musicians, Coders)
They show off the programmer's abilities (Fast
and complex 3D scenes, complex motion, etc.)
Demos are an art form. They blend mathematics,
programming skill, and creativity into something
incredible to watch and listen to. Demos are very
close to music videos beside the fact that (in
most cases) the code is the most important
thing and not the music.
Another form of demos is the Intro.
Actually, the demos originated from intros (used
to be called cracktros in the old C64 and Amiga
days). Originally intros presented a logo of a
group, announcing the new game it cracked, or
published BBSs. Today, however, as the Democcene
is no longer underground and more mainstream,
intros are a common way for a group to show they
can do impressive effects under very pressing
size limitations, mostly in 64kb.
