For the generative text project, I knew that I wanted to create something related to sci-fi, as I've been taking a sci-fi literature class and was inspired by the idea of using generated text and image to explore "the unknown".
As someone who doesn't find writing natural, I began with the image generator. To make the images of the planets, I randomly generated two colors. I then used p5.js' "lerpColor" function to create a gradient between these two that would determine the color palette for each planet. I then used perlin noise to decide the ranges for 3 colors along that gradient. Each planet was also given a random number of moons, and a random radius size. Later on, this became attached to the random moons and radii that the text itself was generating. 
Generating the text itself proved to be a bit frustrating. I first started by generating the name of the planets themselves. The text corpora had a list of planets, and I used wikipedia to find an additional list of minor planets and moons. From these, I randomly generated names for the planets by randomly choosing two names, and splicing random amounts of their characters together. For the name of each system, I simply chose a name from the list.
For the generated text, I used context-free grammar through Rita.js. For each planet, the name, number of moons, moon names, and radius of the planet would be randomly chosen. Then a type of planet (exoplanet, ice planet, terrestrial, etc) would be chosen, and a corresponding climate would be selected. Based on the climate, the habitability and the types of flora and fauna would be selected. Finally, a the generator would choose from a list of possible "other interests" of the planet, such as it being a location that is good for mining, choosing a material from a list from the text corpora of metals.
I would love to revisit this project in the future to dive deeper into the complexity of the generative text. While the results are different from one to the next, they clearly all follow the same structure, which isn't that interesting. I'd be interested to try using Wikipedia's API to potentially use Markov chaining and Rita.js to filter through descriptions of planets from sci-fi novels. I think this project has the potential for something interesting, but it's definitely not there yet.
