For my generative design, I made it design different characters.

Reflection: I programmed unpredictability by having the code randomly generate a number from a certain range and set up a bunch of if/else statements based on what number was chosen. The colors of every feature are also randomly generated (except the mouth and white part of the eyes). The shape of the characters were based on the Among Us characters, since they were simple and cute.
