For this project, I browsed on the internet in search for parametric equations that could be embedded within the code, and after some search found the “infinite loop” sign that I was able to use. To create some dimensionality, I altered the color values in order to change the greyscale. Also, for the background part I happened to change values and created a similar “noise effect” as the background.

I also experimented with different proportions that led to different results, such as this one. If I had more time I wish to play with the details more to achieve a better landscape-like picture.
