I started with the idea behind one of my earliest fxhash projects, [k-NN!](https://www.fxhash.xyz/generative/6549), where colored points (seeds) are randomly scattered onto a 2D canvas to influence the colors of pixels around them. Unlike k-NN! where each pixel's color was inferred based on many neighboring seeds to create a faceted look, EDDY uses a voronoi algorithm to define a cell around each seed, then fills the cell with a gradient. The gradient is based on the cell's seed color and the color from one of its nearby seeds chosen at random.&#x20;

To improve the composition, I added a random centroid to the canvas that attracts the seeds to it.&#x20;

![cells near the centroid are denser and smaller](ipfs://QmYdPrjJdG5fT4cACCpASxRe5xiWnDP8UuHpmBAkexGAJk)

I really liked these outputs and that's why you can press "r" in EDDY to see them.  However they didn't feel happy enough to me. I tried applying a fractal based warping using some of my code from Elswhere Atlas, and the outputs reminded me of [Volatile Moods](https://www.fxhash.xyz/u/Volatile%20Moods)' beautiful project Slumbers. I liked the playfulness of the outputs, but the overall look still didn't feel right, so I decided to explore different warping methods to create a circular fluid feeling.&#x20;

$$
a * maxAngle * cos(b * PI/2)
$$

The basic idea is simple, translate each pixel by an amount based on its distance to the center, along the equidistant circle.  I used the equation above where 'a' is a function of the normalized distance and 'b' controls how much to move the pixel.  Varying 'a', 'b', and maxAngle can achieve a variety of different swirling effects.  &#x20;

I can write a lot more about other aspect of the project such as colors, texture, and optimizations, but I think this is enough for one article. I'll leave you with a couple of small undocumented features.&#x20;

When it started to get cold in California and the sky was often gray with rain, I wanted to add some more colors to my life.  EDDY started as a project just for me, to brighten up the walls and rainy mornings.  I fell in love with the initial outputs and it evolved into something more.  Here I will share some work-in-progress images, technical details, and a couple of secret keys to change the output.

I create digital art with geometric shapes and parametric curves, using lots of math, some physics, and occasionally some machine learning. I also buy art that I like.
