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.
They are called the concertino.
The term that describes the optical trick of swelling columns at midpoint, which was used in the design of the Parthenon is entasis.
If you take a look at the ancient Greek columns, you will see that they are a bit wider in the middle - so the column is not completely straight, but rather swells up in the middle so as to "correct the visual illusion of concavity." It was often used by artists in the ancient Greek times.
