Background
Clusters refer to the accumulation or movement of objects or ideas to positions of proximity to one another. Such clustering may involve one or more center attractors. Clustering seems to involve some sort of attraction that brings objects or ideas together.

Examples
- In science: plant growth in particular location, clusters of stars, lichen growth on a particular part of a rock, mold and bacterial growth, bird flocks, colonial organisms, etc.
- In architecture and design: building plans that provide space for people to gather; office spaces or rooms in a home that come together around a common space; automobile controls and feedback dials on dashboards; placement of plants and objects in landscape design; etc.
- In art: movement apart and together in drama and dance; pictorial representations of alternating space and clusters; etc.
- In social sciences: town and city development; tribal, community, and nation development; clustering of ideas within a conceptual space; formations of cities and town; family structures; cliques; gangs; etc.
- In other senses: cultural and religious events and gatherings; parties; groupings of people in a variety of settings and contexts; etc.
