Starry Night Flow Field
Version 1: The flow field is based on the brightness of the painting. If the area is darker, the field vector is more horizontal, while the area is brighter, the field vector is more vertical. The flowing particles are mimicking the stroke of the original painting. It will feel like the particles are turning with a steering force when it reaches the bright area.

Version 2: Particles will match color with where they are on the original painting. It will feel like the particles are seeking for light.
