For this project, I wanted to lean especially simple and elegant. Arguably, this might have been one of the most off-kilter process thus far in the class— I started with the intention to do simple, but subtle shapes. I wanted to impose 3D spheres onto the generative landscape, and apply a small gaussian blur to create a greater sense of focus.. but alas, I failed to find how to apply both the blur and the 3D implementation. I had explored and programmed using Perlin noise methods,  and considered multiple ways to apply blur (including generating from an array of images).

I think if I had more time, I would be able to find a method to implement these techniques on top of one another (the noise, with the landscape, with 3D on top), but in this case, I had to scale back.

In doing so, I think I learned a valuable lesson that I should have started small, and worked towards my bigger goal. Scaling back was mildly disappointing.
