For this project I went back to a time when I was in Banff, Canada. I would canoe or ride in a boat on the lake with the mountains behind me. I created moving mountains and moving ocean waves with boats of random colors popping in and out. It was tough at first to figure out how to code the objects, but it was a fun project and I am happy with the final product.
