I had a lot of fun working on this project. I wanted to create a desert landscape, so I selected colors from an image of the grand canyon. I made the background sort of have a gradient to give more of a “never ending stretch of land” horizon line feeling. The cactuses were a fun addition that I created in p5.js before realizing that I could’ve made them in illustrator and uploaded them as image files. Upon realization, I decided to add the moving camel. The original gif is from here, but I took each frame and edited it in illustrator to make it look more uniform in my code.
