For this module, I mainly use the Node Code box to execute the ripples. The first step was creating a grid; I started off with a small grid to avoid crashing my computer. This resulted in my two pebbles being very close together.
I was initially attempting two use the code boxes and the nodes to figure out how to combine the two pebbles. I realized this was much harder than I expected since it didn’t work for me after a couple of tries. I ended up using the node box for the rest of the exercise.
