In this assignment, we were tasked with creating designs in Processing using basic functions, the turtle library, and our L-Systems from L1 to laser cut and etch small 5×5 designs.

part 1 – basic library and turtle

For this part, I decided to combine etching and cutting to make a couple Avatar the Last Airbender themed pendants. I took inspiration from the 4 bending symbols, and I made air and earth (the top 2 ones).

To make these designs, I started with a plain circle from the processing library, then the spirals were made in a for loop, with the distance increasing every iteration so it gave a spiral effect. It took some trial and error with the numbers to figure out what was the best strategy. The earth symbol was made in the turtle library, I used the forward(), right(), left(), penUp(), and penDown() functions to create the outline. Here is what I came up with:

code for air design:

code for earth desgin:

I etched around the design and left the design and the border the original wood. Here is the fabrication:

part 2- L-system

for my l-system, I found inspiration from the website: https://paulbourke.net/fractals/lsys/ that had a database of already made l-systems. I wanted to make one that was snowflake-esque and when cut had pieces that all connected. This is what I came up with:

code:
