This composition creates a moving particle system with a smooth color gradient that is affected by Perlin noise. The particles move randomly based on the noise values, causing a chaotic yet structured movement across the canvas. The colors change gradually between three preset color values. The resulting visual effect is an abstract, dynamic pattern of dots and lines that constantly shifts and evolves over time. The code allows for customization of the number of particles, color values, and other parameters to create a variety of different patterns and effects.
