For my project, I made a dynamic drawing that is controlled by the mouse, or the user. I varied several elements, including size, color, rotation and position.
The user can move the wrecking ball to wherever in the canvas and manipulate the size of the buildings. One can see that the size of the ball itself changes, according to position as well. The size of the wrecking ball is largest when the mouse is located on both extremes of the width. The height of the buildings decreases when approached by the ball.
As for colors, as you move the mouse from left to right, the background changes from dark to light.
Another element that the mouse controls is the particles floating in air. It could be considered stars or dust. When the mouse is in the bottom half of the canvas, the particles rotate at a faster pace than they do when the mouse is in the top half of the canvas.
I would say that some challenges came from how tedious my design was. I also wish that I could have made the windows on the buildings to change color in the same fashion that the background does to keep it more consistent.
