# Kinetic Art (キネティック・アート)

> Work defined by the condition that it actually moves, or that its image changes as the viewer moves. Mobiles, motor drives and layered grids producing moiré make time a structural element of the work. The foundation of the idea that motion itself is something to be designed.

- IndexStyle No.474 — https://indexstyle.org/styles/kinetic-art
- Kind: Style · Family: Perceptual Art · Era: 1950s–1970s
- Mood: Exhilaration, Technology
- Color cues: #e9e6dd / #67635d / #171615 (cues taken from reference works, not a fixed palette)

## Defining characteristics

- Actual movement by wind or motor
- Moiré produced by layered grids
- Images that change with the viewer's position
- Repeating modules

## Best used for

- Interactive signage and lenticular print that changes with the passer-by
- Motion identities and installations where the logo literally moves

## Research method

This entry records a historical style; derive the treatment from its sources rather than a fixed recipe:

- Neutral modular sans that survives distortion and overlap
- Repeated modules and layered grids engineered for interference and parallax
- Metal, acetate or screen layers in high-contrast black and white with sparing primaries

## What to avoid

Avoid motion as mere decoration on a static design—if removing the movement changes nothing, the work was never kinetic.

## Application checklist

Before calling a piece an application of this style, check it against the defining characteristics:

- [ ] Actual movement by wind or motor
- [ ] Moiré produced by layered grids
- [ ] Images that change with the viewer's position
- [ ] Repeating modules
- [ ] At least one reference work below has been studied directly
- [ ] The caution above ("What to avoid") has been addressed

## 日本語

実際に動く、あるいは見る者の移動で像が変わることを条件にした造形。モビール、モーター駆動、モアレを生む重ね格子が、時間を作品の構成要素にする。動きを設計対象として扱う考え方の基礎。

特徴: 風やモーターによる実際の運動／重ね格子が生むモアレ／視点移動で変化する像／反復するモジュール
注意: 表面的な記号へ還元せず、時代・地域・技術・制作主体の文脈を確認する。
