For this project, I wanted to create a landscape capturing space. I used clip art for a few of the objects here. The meteor moves past the screen at the beginning of the animation. The objects that move with the camera are the stars, the planets, and the moon surface. The stars are created by randomly placing points with different sizes and slightly different colors. The planets have random sizes and locations as well. For the moon surface, I referred to the stock market example that we did in lab previously. I had originally planned to add craters to the moon, but decided not to for the sake of time. Here is my sketch for this project:
