## When to use it

Describe many new instances continuing to appear.

It describes a continuing supply, not merely a large fixed total.

## The image & its use

Layers suggest one group appearing after another, while the ending stresses that the supply seems inexhaustible. The expression can describe new ideas, useful tools, or unexpected questions during a project. It may sound admiring or tiring depending on the subject. A changing stream is central to the image: the listener keeps encountering another instance. Use a concrete noun to show what is emerging and whether the continuing novelty is welcome.
