This document discusses the demoscene, a computer art subculture focused on creating short demos or demonstrations of programming skill and audiovisual design. It explores the history and evolution of the demoscene from its origins on platforms with hardware constraints like the Commodore 64 to modern demos with self-imposed constraints. Key aspects covered include the motivations of competition, technical challenge, and socializing; constraints related to platforms, file sizes, and visual styles; and the progression of graphics and music capabilities within the demoscene from early platforms to modern tools. Examples of notable recent demos are provided to illustrate the creative approaches and aesthetics within the newschool demoscene.

1. Demoscenen
hackere, constraints, æstetik og designprocesser

2. Eftermiddagsorden
Hvad er demoscenen?
(historisk baggrund, hvad er formålet, hvordan foregår det
konkret, relation til digital æstetik, computere som et ikke-
kvalitetsløst materiale - konkrete eksempler (bl.a. c64, amiga,
PC)
Oldskool vs newschool constraints
Tools & designprocesser
En række cases der highlighter forsk. constraints

3. Hvad er demoscenen?
Computer art subculture
Creating ‘demos’ running 3-4 minutes
Multidisciplinary efforts
Attracts both musicians, graphicians, programmers, and a
legion of hangers-on, organizers and the likes.

9. Motivation: Competition

10. Motivation: Technical Challenge

11. Motivation: Socialising

12. Constraints

13. Hello, this is 64k dog!

17. The culture
Nogle demonstrationer af hvad der foregår i kulturen.

18. Oldskool, newschool,
self-imposed constraint
Oldskool: hardware constrained
3 channel SID (C64)
fixed system palettes (e.g. Spectrum, C64)
4 channel 22Khz (A500)
memory and storage constraints
… and so much more
Newschool: self-imposed creativity constraints
file size constraints (e.g. 1k, 4k, 64k)
colour / palette constraints (e.g. 16 cols)
voluntary (self-imposed) submission to arcane hardware constraints
“64k showdown”
“Epic Rubber Vector” challenge
