My wallpaper is meant to be an abstract representation of the sun rising behind a pyramid. I vaguely remember seeing a wallpaper at a museum that represented the Pyramid of Giza using two like-toned triangles. Starting with that idea, I played around with layers of overlapping shapes and colours.

In the process, I found it much easier to control the shapes’ position after setting a tile length variable. I am happy with the way it turned out using just triangles and one circle per tile. Even though I like the abstraction and simplicity, I’d like to explore more organic forms in future projects.
