Building a sample for the final presentation

I placed an order for all missing parts of materials to build the virtual ecosystem. Building a deliverable sample was the key to this process, so I began to make miniature houses, buildings, cars, and other elements to build a city of Pittsburgh. Once I finish building the city, I build the cylinder to blow air to blow the butterfly in the air. Sending air to one direction was challenging in this process, so I built a flower shape of funnel to drive air to the center. Once each part works at a satisfactory level, I edited the code to add the variable of wind; 10 = low, 20 = medium, and 30 = strong.
