I started by creating a grid and then creating a maze like pattern based on a random toggle (i.e. if the line goes \ or /). I wanted to create a more fun pattern so I added to the conditional to add a flower or a dot in the places where there was no line. I was challenging myself to find a balance between structure and randomness. There’s also a random color associated with each graphic that is placed in the grid. Hence, every time you click your mouse a completely new wallpaper is drawn unlike the one before.
