gossamer-1
—Installation /2006
[ concept ]
"gossamer-1" is a painting installation with the machine that is mounted hot melt adhesives and generates the abstract painting automatically.
This robot is a simulator of Jackson Pollock and his action painting. Its purpose is to looking Expressionism panting of the 20th century over again. And think of creative action of human.

[ mechanism ]
The machine is hanged from the ceiling. And this part works as a header (like a printer plotter). And a canvas is placed under the header. Four headers have cylinders that keep glue sticks in. They push glue sticks out and melt them, and draws a picture.
"gossamer-1" runs by means of sound around the room. The sound of the room are picked up by a microphone, and analyzed with digital sound processor on a PC. "gossamer-1" is controlled by result of its process.
For example, Different colors respond to different frequency of sound. Four bands of frequency are compared each other. And it decides which color the machine pushes out.
And the upper machine has the swing arm connected with the wire. Then, if attack sounds are detected, it pushes the wire and starts a pendulum movement.
During drawing materials are falling down, they are influenced by the phenomenon such as air-conditioning, the person in the room, or wind from outside the room. And always change its patterns organically.
It takes about five hours or a day (depends on the size of a canvas) to finish a picture.
gossamer-1は抽象絵画を自動生成するマシンによる絵画インスタレーションである。マシン（gossamer1）は天井から吊るされており、作品を展示している空間の音を解析し4本あるグルーガンにそれぞれ高音域、中音域、高音域、さらにその上の高音域の周波数を対応させグルーを押し出していく。
グルーはカンバスに落ちるまでに部屋の空調や人の動く時に起こる風などに影響されてオーガニックに変化する。それぞれのグルーガンには1色ずつの色が配置されていて部屋の音環境がグルーの出方に影響を与える。
また、周波数の他にアタック音を解析していて一定の条件が揃うと吊るされたワイヤーにつながったスイングアームが回転して振り子運動を始める。時間とともにグルーが堆積することでカンバスに半立体の抽象画を描いてゆく。
