Answer:
kinetic art
Explanation:
<u>Kinetic art presents an art form that considers movement, the changes in the wind, and multidimensionality</u>. It is usually the form of sculpture that is presented in the air and can move naturally or by a technological device. The motion of the installation is part of the artistic concept and experience, and the changes in the piece are a vital part of the presentation and observation.
The art here presented is kinetic as it is hanging on the tight line and probably <u>changing the motion</u>. The colored pieces on it might also be changing, or they just might all be turning around in the air, changing the expression.
People can contribute different things because different people have different strengths, and when one has an idea the other(s) can build on to that idea. When there are 2 or more people working on a project, it becomes better than it would be if the project was being worked on individually. The work has more potential.
