Mikko Wilkman: "The Incredible IFS-System", 2003

:. more from the same artist



The piece is based on the famous Iterated Function System fractal algorithm. As the name implies, the algorithm is based upon iteration. Thousands of iterations are performed on a coordinate point while changing the coordinates through a series of multiplication and addition selected at random from a predetermined set. The demo adds trigonometric operations, polar coordinate conversions and changes in the colours of the coordinate points. As a result, new qualities are constantly introduced to the fractal image. The interesting aspect of the demo is that the programmer has hardly any control over the end result. He or she only gives a set of limits to the algorithm, within which the computer generates the image from random numbers. Each image is unique and transitory, because it is not recorded anywhere in the computer. Consequently each viewing experience is different and new.

:. more demos from the artists

This demo is part of a "Mega Demo" consisting of several sections. This part has all the typical elements of classic first-generation demos and intros, the most important being the horizontal scrolling text band. Other classic features are the moving colour blocks behind the waving logo, floating animated letter (B) "sprites", and equalisers throbbing in rhythm with the music.

Virtual Dreams: "Chaosland", 1993

:. more demos from the artists

Chaosland was originally programmed for a demo competition where the maximum allowed size of the demo was 40 kilobytes. The size limitation does not detract from the impressiveness of the demo, on the contrary: it is the external limitations that make demo programmers surpass themselves, write extremely streamlined code, and make the primitive computers do something unprecedented. Special features in Chaosland include music squeezed into a very small package and the chaos zoomer effect that has already become a classic. An extremely rare feature is the use of a naked male instead of a female figure.

The demo introduced a new style using texts superimposed on visual effects. 3D mazes, familiar from the PC game Doom, was one of the few effects that were adopted from the PC world to Amiga - generally it was the other way round. The music can no longer be compared with the melodic tunes made with the 4-track tracker software. The demo bends the genre clearly towards experimental electronic music. Remixes of demos are rarely released, but minor updates are possible, for example, for fixing bugs in the programme.

Lapsuus won the first prize in the demo series at Assembly 2001. All demos programmed for the more efficient PCs came second. The demo pays homage to the artists' childhood computers, making full use of the features of current demos related to animations and music videos. Unlike modern PC demos, however, the magic of the real-time 3D piece comes from the programmers' skill to make the primitive Amiga computer reach new heights.

katastro.fi: "godog", 1998

.: watch the demo online
:. more demos from the artists


godog is programmed with Java and can be viewed with an Internet browser. Using new programming languages to replicate classic early effects and objects is very typical of the demo scene. Each new language is a challenge to the programmer. godog uses textual narrative superimposed on visual effects, a relatively seldom used genre. The narrative element in demos is generally audiovisual, and textual elements are either insider messages for the community, or included simply because they look good!

:. more demos from the artists



Utilising the OpenGL graphic interface, this piece was originally programmed with Java, but was the first demo to be converted to Microsoft .Net architecture. The music with its vocals is a far cry from classic demo music. Unlike tracker tunes, it no longer consists of sequenced samples played in real time, but of a single mp3 playback file.

TPOLM: "The Day The Earth Was Born", 2000

.: download the demo
:. more demos from the artists


This demo exploits with elegant simplicity a classic effect typical of the group, the tunnel. The use of a single effect in perfect synchronisation with music shows that interpretation also has a place in demos and programming. In addition to typical insider lingo, the basic message of the piece, "Your Mother is a Motherfucking Giraffe", makes no bones about the authors' intentions. The viewer must be content with the fact that it sounds good.

Orange: "The Nonstop Ibiza Experience", 2000

.: download the demo
:. more demos from the artists


This demo represents the experimental style typical of its authors, combining the use of low resolution as a stylistic effect, visuals carefully synchronised with the music, and 2D graphics that combine idiosyncratic comic-strip style with Surrealist effects. The structure of the piece is reminiscent of the narrative device of early demos, where effects and images are presented in separate sections.

Komplex: "Shine", 2002

:. more demos from the artists


Another usual restriction in demo competitions, in addition to size, is a time limit. Shine was one of the top three Assembly winners in the 24h series, where the demo had to be completed within 24 hours. Made to be viewed with a mobile phone, the demo includes a sinus scroller, a classic demo effect required in the original competition brief.

Limbo won the mobile demo series in Assembly 2002. New platforms with limitations, such as mobile devices, offer new challenges to demo artists. As the power of PCs and 3D graphics adapters grows, the programmers' interest is drawn to new environments offering new areas to be conquered and demanding creative problem solving.

The demo for Nokia 7650 was made for this exhibition, where it received its world premiere. The Zip package also includes a PC version! The demo includes several classic Amiga effects, such as an endless zoom into a fractal and 2D bump mapping, where the structure of a surface is revealed by a moving highlight. In classic "old skool" style, the demo introduces a brand new effect, in this case a 3D object with glowing highlights rendered with the radiocity method. The demo also utilises several post processing effects, such as radial blur, used to create the impression of a light source shining behind the surface, and median filter, used to level the image and reduce noise.

This demo attracted a lot of attention immediately after its release for the innovative way it combines 2D and 3D graphics. The effects are presented simultaneously on several layers at once, instead of separate effect sequences. The work is a prime example of how important planning, directing and editing can be in a demo. The demo was previously presented at the Sonar festival in Barcelona in 2002.

Mikko Karvonen: "Teonanácatl", 2003

The demo scene introduced a new way of making music on a home computer. The so-called tracker programmes offered the possibility of using your own samples and an easy way of inputting notes. Because of small memories and slow processors, the first samples were in 8-bit format and, even at best, recorded at 20 kHz sampling frequency. Yet they were extremely usable and a considerably cheaper alternative to expensive synthesisers or other MIDI devices. Sample diskettes made by amateurs soon spread around the world. The sound work over the Kiasma main entrance uses such classic samples and effects with contemporary post processing.
