Marc Marc, September 1991
Art Moderne installation

The Art Moderne Installation was exhibited for the first time in Holland in the Canon Image Centre, September 1991, as part of a group exhibition of four artists whom all were using the computer in a different way to create their Art. The title of this exhibition was 'Computer Generated Manipulated Images'. Although this title text was located prominently aside the Art Moderne Installation it hardly covers the concept of it.

Marc Marc - MarcMarc MD artist - photo: overview installation The Art Moderne Installation was showing a graphic 'symphony' of 26 composure structures in a cycle of 90 minutes. Each computer was running individually an identical software programme (Art Moderne software) that consists of Auto Composing algorithms. These algorithms represent concepts on how to act (as an abstraction) to create continuously graphic images. The computers also were interconnected (through MIDI ports) to have the choice of the algorithms controlled by one Master computer and to synchronize the time sequence of the total view of actions at the individual computers.

Testing the Art Moderne Installation.

The 9 computers to set up the installation were sponsored by COMMEDIA Amsterdam and ATARI BENELUX. I received them at home 3 weeks before the exhibition would take place to test my software running with the 9 computers interconnected by MIDI and to compose the graphic 'symphony'. The first problem that appeared was due to the fact that the computers were all new. When they were switched on, they filled the air with a dirty smell that made me dizzy within 1 hour. This made the programming quiet to be a hallucination.

Nevertheless it was very exciting to view the process of Auto Composing on 9 monitors at the same time. The maximum that I had so far were only 3 monitors. However each computer is running the same software, they all produce unique variations within each 'style frame' (algorithm). Within some styles the different results start to be close to each other and 'slowly' mutate towards something completely different. Some other styles produce great differences straight away. The more computers are running at the same time with the same algorithm, the more interesting it becomes to view the creating acts.

Marc Marc - MarcMarc MD artist - the installation Another problem that appears when presenting an installation like this, is the reliability of both the hard and software. It must operate for weeks without errors and it must be switched on each day by somebody that does not know about any technical details. The computers needed to be switched on in groups of three each. Each computer then starts to auto load its software and then waits for 20 second before its starts to send out some MIDI codes. All computers are MIDI interconnected as a ring. This means that each code that is send is received by the next computer in the ring and also seen by the software. The software then sees whether this information needs to be used or to be send through to the next computer - until it reaches its destination. This means that the codes that are send do have ID information that determines the destination computer. But, when starting up non of the computers know which ID they have. Also, one of the computers must act as a master while the others must act as slaves to this master.

Marc Marc - MarcMarc MD artist - The installation Because all nine computers have identical software, that does not say who the master is, the MASTER FIGHT was invented. When the computers start up they are all equal and each of them start to play a numeric random game. The results of this game are send to the next computer in the ring. This one sends it also to the next one and so on. Thus, they all know from each other which numbers they chose sequently. One number is the winning one (this number is also randomly chosen by all of them and reduced to a single 'bingo card'). At a certain moment one computer has the bingo number and the others are seeing this and thus decide to have their master chosen (when two computers have the bingo number at the same time, they simply continue fighting with each other until one is left). At the end of the game the master is known and the graphic 'symphony' can start.
The progression in the 'Master fight' also is visualized on the monitors. The screens are vibrating by varying the vertical size of a white band across the screen as an translation of the numerical values that the software chooses. Although simple, it creates a living view on the installation.

The system of interconnecting all computers as a ring has the advantage that (together with its software implementation) the amount of computers may vary to any amount. The 'Master fight' protocol also finds out how many computers are connected. When a computer does not respond to incoming information after a certain time out and several retries, it switches to an individual mode to act as a STAND ALONE device and thus is not a member anymore of the Master/Slave team. This also could happen because the connection wiring does not function or one computer has dropped out.
