Algorithm generates a conus textile shell pattern. Select % deviant blank and steps between tiles. Each time you click flag, a slightly different pattern shows. Press "R" to see real textile shell. Spacebar to see the pattern simulated on the full screen.
This is a math inspired project, as the pattern generating algorithm is the main point. "Textile" Cone Shells often have this chevron pattern. Halloween Hermit Crab (shown in image) often adopt these shells. But a venomous sea snail originally made the shell for itself. We used this as an art and science project using watercolor paints and coding. We painted the crab and devised the algorithm that reproduces the shell pattern. Essentially the rule for making this pattern is: Create a row of dots. Some randomly selected dots are red. Then move down a row and follow a simple rule of change. The rule is elementary cellular automata rule 18 (creates the shell pattern). Rule 90 is similar but creates a Sierpinski triangle. Music: La Mer (The sea) II.
