# Fluid vortices

Visual style (Techniques)
Source: https://visual-gallery.asami.tokyo/en/styles/fluid-vortices

A flow shedding alternating vortices behind an obstacle (a Kármán vortex street), drawn with glowing streamlines.

## Palette
- #06070D Obsidian (~76%)
- #36E2F2 Cyan (~10%)
- #F04BB4 Neon magenta (~10%)
- #2A2A7A Deep indigo (~4%)

## Visual traits
- A round obstacle sits on the left; the flow passes it from left to right
- Behind it, vortices form two staggered rows that spin in opposite directions
- Thin streamlines curl around each vortex; one sense of rotation is magenta, the other cyan
- Glowing lines and particles are drawn with additive blending on a near-black background, so overlaps get brighter and bloom
- In motion, the vortices drift downstream while the streamlines flow

## Prompt
Fluid vortices: a Kármán vortex street behind a round obstacle on the left, two staggered rows of counter-rotating vortices drawn with thin glowing streamlines that curl around each vortex, magenta for one sense of rotation and cyan for the other, on a near-black background with additive blending. As video, the vortices drift downstream.

## Avoid
ocean photo, smoke photo, turbulent noise without structure, white background, cartoon waves
