When I started working on this project, I wanted to use the honeycomb code from Assignment B this week because of how interesting that ended up looking by itself. Ultimately I had to simplify it in order to make the math for the rest of the design work out a bit better, as adjusting everything to deal with the square root of three over two can become a difficult task. The shapes’ randomized fills and stroke correspond with each other and utilize the same random value in different ways.
