4.Cellular Automata Music
Cellular automata Music beta2D-1.0
MOCA-cam

Time:31.Oct, 2007
Venue:Taipei MOCA

Inspired by “Game of life”, the interactive mode created by the english mathematician John Cornway, “Cellular Automata Music” is the 2nd experimentation of applying musical algorithm/mechanism to the creation of sound through human interactivity.
Basic Rules:Audience are invited to the seats in the matrix(see upper picture) ,each audience has 4 different noise instruments in hand.The audience can freely choose which instrument to play in the first “act”.The changement of the “acts” are indicated by a flag in the middle of the matrix in a interval between 3-20 second,the audiences should change/keep the instrument for each new act, according to his/her 4 neighbors’ instrumental choice:if 3 or 4 of them hold the same instrument ,follow neighbors’ choice in next “act”,in case 2 of them hold the same as you do,do not change the instrument,if only one or none of them hold the same instrument as you do,change the instrument in the next act.

Cellular automata Music beta2D-1.2
DM-07-02
Time:17,Nov,2007
Venue:Boyo fondation,Puli
beta2D-1.2 is the first improved version made for Boyo Fondation.
several vital bugs were fixed:
1.audience sit in spinal circle instead of matrix, audience reacts only to the neighbors
in left、right and front.
2.when the same instrument is played 3 times,stop to play.

Cellular Automata Music beta2D-2.1

Liquid Architecture-polyphonic social
Time:14,Mar,2017
Venue:,abbotford,Melbourne

36 performers enter the theatre in succession, sit down and form a 6 *6 square dot formation. They start to interact following the theory of “Cellular Automata”. When the temple block is struck, they will have do one movement (or similarly, when all the flashlights shine at the same time). Before the first movement, each cell will choose its own musical instrument (considering tone and sound, we provide four kinds of small musical instruments that can more easily achieve harmony). Each kind of musical instrument has a corresponding fixed repetitive set of movements. Each movement after the second move will depend on their own decisions together with their four neighbors’ decisions (those in front, back, left and right) to decide what the movement and musical instrument are going to be. For instance:

1.If the musical instrument you choose is different from all your neighbors, then you have to play this same instrument for three goes and then stop playing forever.

2.If the musical instrument you choose is the same as only one of your neighbor, then change to another instrument at the next go.

3.If your musical instrument is the same as two or three of your neighbors, then you play the same one on the next movement. When you play the same instrument more than three times, you will have to stop playing forever.

4.If the musical instrument you choose is the same as all of your neighbors, you have to stop playing forever at the next go. This will then become a piece of music with the tone continuing to change and evolve slightly. This principle can also apply to the change of body movement of a group.
